Pull was never meant to take --dry-run at all. However, it
passes unknown arguments to git-fetch, which does do a
dry-run. Unfortunately, pull then attempts to merge whatever
cruft was in FETCH_HEAD (which the dry-run fetch will not
have written to).
Even though we never advertise --dry-run as something that
should work, it is still worth being defensive because:
1. Other commands (including fetch) take --dry-run, so a
user might try it.
2. Rather than simply producing an error, it actually
changes the repository in totally unexpected ways.
This patch makes "pull --dry-run" equivalent to "fetch
--dry-run".

This function takes a sha1 and produces a loose object
filename. It caches the location of the object directory so
that it can fill the sha1 information directly without
allocating a new buffer (and in its original incarnation,
without calling getenv(), though these days we cache that
with the code in environment.c).
This cached base directory can become stale, however, if in
a single process git changes the location of the object
directory (e.g., by running setup_work_tree, which will
chdir to the new worktree).
In most cases this isn't a problem, because we tend to set
up the git repository location and do any chdir()s before
actually looking up any objects, so the first lookup will
cache the correct location. In the case of reset --hard,
however, we do something like:
1. look up the commit object
2. notice we are doing --hard, run setup_work_tree
3. look up the tree object to reset
Step (3) fails because our cache object directory value is
bogus.
This patch simply removes the caching. We use a static
buffer instead of allocating one each time (the original
version treated the malloc'd buffer as a static, so there is
no change in calling semantics).

Add a $toplevel variable accessible to `git submodule foreach`, it
contains the absolute path of the top level directory (where
.gitmodules is).
This makes it possible to e.g. read data in .gitmodules from within
foreach commands. I'm using this to configure the branch names I want
to track for each submodule:
Maybe there's a less painful way to do *that* (I'd love to hear about

know what the top-level is from git submodule foreach.

As with the option -c/--count, git grep with the option -l/--name-only
should work the same with binary files as with text files because
there is no danger of messing up the terminal with control characters
from the contents of matching files. GNU grep does the same.
Move the check for ->name_only before the one for binary_match_only,

Coloring the extended headers where done as a whole not per line. less with
option -R (which is the default from git) does not support this coloring
mode because of performance reasons. The -r option would be an alternative
but has problems with lines that are longer than the screen. Therefore
stick to the idiom to color each line separately. The problem is, that the
result of ill_metainfo() will also be used as an parameter to an external
diff driver, so we need to disable coloring in this case.
Because coloring is now done inside fill_metainfo() we can simply add this
string to the diff header and therefore keep the last newline in the
extended header. This results also into the fact that the external diff
driver now gets this last newline too. Which is a change in behavior
but a good one.

Change the semantics of the "crlf" attribute so that it enables
end-of-line normalization when it is set, regardless of "core.autocrlf".
Add a new setting for "crlf": "auto", which enables end-of-line
conversion but does not override the automatic text file detection.
Add a new attribute "eol" with possible values "crlf" and "lf". When
set, this attribute enables normalization and forces git to use CRLF or
LF line endings in the working directory, respectively.
The line ending style to be used for normalized text files in the
working directory is set using "core.autocrlf". When it is set to
"true", CRLFs are used in the working directory; when set to "input" or
"false", LFs are used.

autocrlf: Make it work also for un-normalized repositories
Previously, autocrlf would only work well for normalized
repositories. Any text files that contained CRLF in the repository
would cause problems, and would be modified when handled with
core.autocrlf set.
Change autocrlf to not do any conversions to files that in the
repository already contain a CR. git with autocrlf set will never
create such a file, or change a LF only file to contain CRs, so the
(new) assumption is that if a file contains a CR, it is intentional,
and autocrlf should not change that.
The following sequence should now always be a NOP even with autocrlf
set (assuming a clean working directory):
git checkout <something>
touch *
git add -A . (will add nothing)
git commit (nothing to commit)
Previously this would break for any text file containing a CR.
Some of you may have been folowing Eyvind's excellent thread about
trying to make end-of-line translation in git a bit smoother.
I decided to attack the problem from a different angle: Is it possible
to make autocrlf behave non-destructively for all the previous problem cases?
Stealing the problem from Eyvind's initial mail (paraphrased and
summarized a bit):
1. Setting autocrlf globally is a pain since autocrlf does not work well
with CRLF in the repo
2. Setting it in individual repos is hard since you do it "too late"
(the clone will get it wrong)
3. If someone checks in a file with CRLF later, you get into problems again
4. If a repository once has contained CRLF, you can't tell autocrlf
at which commit everything is sane again
5. autocrlf does needless work if you know that all your users want
the same EOL style.
I belive that this patch makes autocrlf a safe (and good) default
setting for Windows, and this solves problems 1-4 (it solves 2 by being
set by default, which is early enough for clone).
I implemented it by looking for CR charactes in the index, and
aborting any conversion attempt if this is found.

If we know we are creating a bare repository, we use setenv
to set the GIT_DIR directory to the current directory
(either where we already were, or one we created and chdir'd
into with "git init --bare <dir>").
However, with "git --bare init <dir>" (note the --bare as a
git wrapper option), the setup code actually sets GIT_DIR
for us, but it uses the wrong, original cwd when a directory
is given. Because our setenv does not use the overwrite
flag, it is ignored.
We need to set the overwrite flag, but only when we are
given a directory on the command line. That still allows:
GIT_DIR=foo.git git init --bare
to work. The behavior is changed for:
GIT_DIR=foo.git git init --bare bar.git
which used to create the repository in foo.git, but now will
use bar.git. This is more sane, as command line options
should generally override the environment.
