Introduce is_utf() to check if a text looks like it is encoded
in UTF-8, utf8_width() to count display width, and implements
print_wrapped_text() using them.
git-commit-tree warns if the commit message does not minimally
conform to the UTF-8 encoding when i18n.commitencoding is either
unset, or set to "utf-8".
Now that Git depends on pread in index-pack its safe to say we can
also depend on it within the git_mmap emulation we activate when
NO_MMAP is set. On most systems pread should be slightly faster
than an lseek/read/lseek sequence as its one system call vs. three
system calls.
We also now honor EAGAIN and EINTR error codes from pread and
restart the prior read.

Display 'theirs' branch name when possible in merge.
Displaying the SHA1 of 'their' branch (the branch being merged into
the current branch) is not nearly as friendly as just displaying
the name of that branch, especially if that branch is already local
to this repository.
git-merge now sets the environment variable 'GITHEAD_%(sha1)=%(name)'
for each argument it gets passed, making the actual input name that
resolved to the commit '%(sha1)' easily available to the invoked
merge strategy.
git-merge-recursive makes use of these environment variables when
they are available by using '%(name)' whenever it outputs the commit
identification rather than '%(sha1)'. This is most obvious in the
conflict hunks created by xdl_merge:
Use extended SHA1 syntax in merge-recursive conflicts.
When we get a line-level conflict in merge-recursive and print out
the two sides in the conflict hunk header and footer we should use
the standard extended SHA1 syntax to specify the specific blob,
as this allows the user to copy and paste the line right into
'git show' to view the complete version.

This is confusing when somebody attempts to do this:
$ git pull origin/foo
which is not syntactically correct (unless you have origin/foo.git
repository) and should fail, but it resulted in a mysterious
access to the 'foo' subdirectory of the origin repository.
Which was what it was designed to do, but because this is an
oddball "feature" I suspect nobody uses, let's remove it.
default pull: forget about "newbie protection" for now.
This will not be backward compatible no matter how you cut it.
Shelve it for now until somebody comes up with a better way to
determine when we can safely refuse to use the first set of
branchse for merging without upsetting valid workflows.
merge and reset: adjust for "reset --hard" messages
An earlier commit made "reset --hard" chattier but leaking its
message from "git rebase" (which calls it when first rewinding
the current branch to prepare replaying our own changes) without
explanation was confusing, so add an extra message to mention
it. Inside restorestate in merge (which is rarely exercised
codepath, where more than one strategies are attempted),
resetting to the original state uses "reset --hard" -- this can
be squelched entirely.
reflog expire: prune commits that are not incomplete
Older fsck-objects and prune did not protect commits in reflog
entries, and it is quite possible that a commit still exists in
the repository (because it was in a pack, or something) while
some of its trees and blobs are long gone. Make sure the commit
and its associated tree is complete and expire incomplete ones.
Don't crash during repack of a reflog with pruned commits.
If the user has been using reflog for a long time (e.g. since its
introduction) then it is very likely that an existing branch's
reflog may still mention commits which have long since been pruned
out of the repository.
Rather than aborting with a very useless error message during
git-repack, pack as many valid commits as we can get from the
reflog and let the user know that the branch's reflog contains
already pruned commits. A future 'git reflog expire' (or whatever
it finally winds up being called) can then be performed to expunge
those reflog entries.

Because I am about to introduce a global warn() function (much
like the global error function) this global declaration would
conflict with the one supplied by imap-send. Further since
imap-send's warn function output depends on its Quiet setting
we cannot simply remove its internal definition and use the
forthcoming global one.
So refactor warn() -> imap_warn() and info() -> imap_info()
(the latter was done just to be consistent in naming).

parse-remote: mark all refs not for merge only when fetching more than one
An earlier commit a71fb0a1 implemented much requested safety
valve to refuse "git pull" or "git pull origin" without explicit
refspecs from using the first set of remote refs obtained by
reading .git/remotes/origin file or branch.*.fetch configuration
variables to create a merge. The argument was that while on a
branch different from the default branch, it is often wrong to
merge the default remote ref suitable for merging into the master.
That is fine as a theory. But many repositories already in use
by people in the real world do not have any of the per branch
configuration crap. They did not need it, and they do not need
it now. Merging with the first remote ref listed was just fine,
because they had only one ref (e.g. 'master' from linux-2.6.git)
anyway.
So this changes the safety valve to be a lot looser. When "git
fetch" gets only one remote branch, the irritating warning would
not trigger anymore.
I think we could also make the warning trigger when branch.*.merge
is not specified for the current branch, but is for some other
branch. That is for another commit.
The logic to decide when to refuse to use the default "first set of
refs fetched" for merge was utterly bogus.
In a repository that happily worked correctly without any of the
per-branch configuration crap did not have (and did not have to
have) any branch.<current>.merge. With that broken commit, pulling
from origin no longer would work.
Now that we have decided to make 'add' behave like 'update-index'
(and therefore fully classify update-index as strictly plumbing)
the am/revert/cherry-pick family of commands should not steer the
user towards update-index. Instead send them to the command they
probably already know, 'add'.

The expiration uses two timestamps: --expire and --expire-unreachable.
Entries older than expire time (defaults to 90 days), and entries older
than expire-unreachable time (defaults to 30 days) and records a commit
that has been rewound and made unreachable from the current tip of the
ref are removed from the reflog.
The parameter handling is still rough, but I think the
core logic for expiration is already sound.
When ref@{N} is specified on a ref that has only M entries (M < N),
instead of saying the initial timestamp the reflog has, warn that
there is only M entries.
Teach git-repack to preserve objects referred to by reflog entries.
This adds a new option --reflog to pack-objects and revision
machinery; do not bother documenting it for now, since this is
only useful for local repacking.
When the option is passed, objects reachable from reflog entries
are marked as interesting while computing the set of objects to
pack.
This corrects minor remaining bits that still talked about <tree-ish>;
the Porcelain users (as opposed to plumbers) are mostly interested in
commits so use <commit> consistently and keep a sentence that mentions
that <tree-ish> can be used in place of them.

Revert "fix testsuite: make sure they use templates freshly built from the source"
This reverts commit 74d20040cafdced657efbf49795183d209a3a07b.
Version from Johannes to introduce GIT_TEMPLATE_DIR is simpler,
although I unconsciously stayed away from introducing yet another
environment variable.
A script to be driven when the user says "git add --interactive"
is introduced.
When it is run, first it runs its internal 'status' command to
show the current status, and then goes into its internactive
command loop.
The command loop shows the list of subcommands available, and
gives a prompt "What now> ". In general, when the prompt ends
with a single '>', you can pick only one of the choices given
and type return, like this:
*** Commands ***
1: status 2: update 3: revert 4: add untracked
5: patch 6: diff 7: quit 8: help
What now> 1
You also could say "s" or "sta" or "status" above as long as the
choice is unique.
The main command loop has 6 subcommands (plus help and quit).
* 'status' shows the change between HEAD and index (i.e. what
will be committed if you say "git commit"), and between index
and working tree files (i.e. what you could stage further
before "git commit" using "git-add") for each path. A sample
output looks like this:
It shows that foo.png has differences from HEAD (but that is
binary so line count cannot be shown) and there is no
difference between indexed copy and the working tree
version (if the working tree version were also different,
'binary' would have been shown in place of 'nothing'). The
other file, git-add--interactive.perl, has 403 lines added
and 35 lines deleted if you commit what is in the index, but
working tree file has further modifications (one addition and
one deletion).
* 'update' shows the status information and gives prompt
"Update>>". When the prompt ends with double '>>', you can
make more than one selection, concatenated with whitespace or
comma. Also you can say ranges. E.g. "2-5 7,9" to choose
2,3,4,5,7,9 from the list. You can say '*' to choose
everything.
What you chose are then highlighted with '*', like this:
To remove selection, prefix the input with - like this:
Update>> -2
After making the selection, answer with an empty line to
stage the contents of working tree files for selected paths
in the index.
* 'revert' has a very similar UI to 'update', and the staged
information for selected paths are reverted to that of the
HEAD version. Reverting new paths makes them untracked.
* 'add untracked' has a very similar UI to 'update' and
'revert', and lets you add untracked paths to the index.
* 'patch' lets you choose one path out of 'status' like
selection. After choosing the path, it presents diff between
the index and the working tree file and asks you if you want
to stage the change of each hunk. You can say:
y - add the change from that hunk to index
n - do not add the change from that hunk to index
a - add the change from that hunk and all the rest to index
d - do not the change from that hunk nor any of the rest to index
j - do not decide on this hunk now, and view the next
undecided hunk
J - do not decide on this hunk now, and view the next hunk
k - do not decide on this hunk now, and view the previous
undecided hunk
K - do not decide on this hunk now, and view the previous hunk
After deciding the fate for all hunks, if there is any hunk
that was chosen, the index is updated with the selected hunks.
* 'diff' lets you review what will be committed (i.e. between
HEAD and index).
This is still rough, but does everything except a few things I
think are needed.
* 'patch' should be able to allow splitting a hunk into
multiple hunks.
* 'patch' does not adjust the line offsets @@ -k,l +m,n @@
in the hunk header. This does not have major problem in
practice, but it _should_ do the adjustment.
* It does not have any explicit support for a merge in
progress; it may not work at all.
blame: -b (blame.blankboundary) and --root (blame.showroot)
When blame.blankboundary is set (or -b option is given), commit
object names are blanked out in the "human readable" output
format for boundary commits.
When blame.showroot is not set (or --root is not given), the
root commits are treated as boundary commits. The code still
attributes the lines to them, but with -b their object names are
not shown.
If there are more than one branches to be deleted, failure on
one will no longer stop git-branch to process the next ones.
The command still reports failures by exitting non-zero status.

I just twisted it not to check fast-forwardness with the current
branch when you are removing a tracking branch. Most likely,
removal of a tracking branch is not because you are "done with"
it (for a local branch, it usually means "you merged it up"),
but because you are not even interested in it. In other words,
remote tracking branches are more like tags than branches.
fix testsuite: make sure they use templates freshly built from the source
