checkout: rearrange update_refs_for_switch for clarity
Take care of simple, exceptional cases before the meat of the "check
out by branch name" code begins. After this change, the function
vaguely follows the following pseudocode:
if (-B or -b)
create branch;
if (plain "git checkout" or "git checkout HEAD")
;
else if (--detach or checking out by non-branch commit name)
detach HEAD;
else if (checking out by branch name)
attach HEAD;
One nice side benefit is to make it possible to remove handling of
the --detach option from outside switch_branches.

checkout: introduce --detach synonym for "git checkout foo^{commit}"
For example, one might use this when making a temporary merge to
test that two topics work well together.

checkout: split off a function to peel away branchname arg
The code to parse and consume the tree name and "--" in commands such
as "git checkout @{-1} -- '*.c'" is intimidatingly long. Split it out
into a separate function and make it easier to skip on first reading
by making the data it uses and produces more explicit.
No functional change intended.

The usual dwim_ref lookup prefers tags to branches. Because
checkout primarily works on branches, though, we switch that
behavior to prefer branches.
However, there was a bug in the implementation in which we
used lookup_commit_reference (which used the regular lookup
rules) to get the actual commit to checkout. Checking out an
ambiguous ref therefore ended up putting us in an extremely
broken state in which we wrote the branch ref into HEAD, but
actually checked out the tree for the tag.
This patch fixes the bug by always attempting to pull the
commit to be checked out from the branch-ified version of
the name we were given.

rebase --skip: correctly wrap-up when skipping the last patch
When "rebase --skip" is used to skip the last patch in the series, the
code to wrap up the rewrite by copying the notes from old to new commits
and also by running the post-rewrite hook was bypassed.
Unlike bash and ksh, dash passes through hexadecimal \xcc escapes.
So when run with dash, these tests *pass* (since '\xcc' is a perfectly
reasonable filename) but they are not testing what was intended.
Use octal escapes instead, in the spirit of v1.6.1-rc1~55^2
(2008-11-09).

Some shells, for example dash versions older than 0.5.4, need to
spell a variable reference as '$N' rather than 'N' in an arithmetic
expansion. In order to avoid the syntax error, we change the
offending variable reference from 'i' to '$i' in function scramble.
There is nothing bash specific to this test script (and we shouldn't
have any bash dependent test). Fix its shebang line.

am --abort: keep unrelated commits since the last failure and warn
After making commits (either by pulling or doing their own work) after a
failed "am", the user will be reminded by next "am" invocation that there
was a failed "am" that the user needs to decide to resolve or to get rid
of the old "am" attempt. The "am --abort" option was meant to help the
latter. However, it rewinded the HEAD back to the beginning of the failed
"am" attempt, discarding commits made (perhaps by mistake) since.
When determine_author_info() returns to the calling prepare_to_commit(),
we already know the pieces of information necessary to determine what
author ident will be used in the final message, but deferred making a call
to fmt_ident() before the final commit_tree(). Most importantly, we would
open the editor to ask the user to compose the log message before it.
As one important side effect of fmt_ident() is to error out when the given
information is malformed, this resulted in us spawning the editor first
and then refusing to commit due to error, even though we had enough
information to detect the error before starting the editor, which was
annoying.
Move the fmt_ident() call to the end of determine_author_info() where we
have final determination of author info to rectify this.
If the user gives "git commit --date=foobar", we silently
ignore the --date flag. We should note the error.
This patch puts the fix at the lowest level of fmt_ident,
which means it also handles GIT_AUTHOR_DATE=foobar, as well.
There are two down-sides to this approach:
1. Technically this breaks somebody doing something like
"git commit --date=now", which happened to work because
bogus data is the same as "now". Though we do
explicitly handle the empty string, so anybody passing
an empty variable through the environment will still
work.
If the error is too much, perhaps it can be downgraded
to a warning?
2. The error checking happens _after_ the commit message
is written, which can be annoying to the user. We can
put explicit checks closer to the beginning of
git-commit, but that feels a little hack-ish; suddenly
git-commit has to care about how fmt_ident works. Maybe
we could simply call fmt_ident earlier?

fill_textconv(): Don't get/put cache if sha1 is not valid
When blaming files in the working tree, the filespec is marked with
!sha1_valid, as we have not given the contents an object name yet. The
function to cache textconv results (keyed on the object name), however,
didn't check this condition, and ended up on storing the cached result
under a random object name.

t7607: use test-lib functions and check MERGE_HEAD
Use the test_commit and test_path_is_missing
functions from the test library.
Also make sure that a merge which fails due to
pre-merge checks aborts properly and does not
leave MERGE_HEAD behind.
The "will not overwrite removed file" test is an
exception to this. It notices the untracked file
at a stage where the merge is already well under
way. Therefore we cannot abort the merge without
major restructuring. See the following thread for
more details.

The "[add] ignore-errors" tweakable introduced by v1.5.6-rc0~30^2 (Add
a config option to ignore errors for git-add, 2008-05-12) does not
follow the usual convention for naming values in the git configuration
file.
What convention? Glad you asked.
The section name indicates the affected subsystem.
The subsection name, if any, indicates which of
an unbound set of things to set the value for.
The variable name describes the effect of tweaking
this knob.
The section and variable names can be broken into
words using bumpyCaps in documentation as a hint to
the reader. These word breaks are not significant
at the level of code, since the section and variable
names are not case sensitive.
The name "add.ignore-errors" includes a dash, meaning a naive
configuration file like
[add]
ignoreErrors
does not have any effect. Avoid such confusion by renaming to the
more consistent add.ignoreErrors, but keep the old version for
backwards compatibility.
