As explained in the documentation[*] this is totally useless on
filesystems that do ordered/journalled data writes, but it can be a
useful safety feature on filesystems like HFS+ that only journal the
metadata, not the actual file contents.
It defaults to off, although we could presumably in theory some day
auto-enable it on a per-filesystem basis.

match_explicit is called for each push refspec to try to
fully resolve the source and destination sides of the
refspec. Currently, we look at each refspec and report
errors on both the source and the dest side before aborting.
It makes sense to report errors for each refspec, since an
error in one is independent of an error in the other.
However, reporting errors on the 'dst' side of a refspec if
there has been an error on the 'src' side does not
necessarily make sense, since the interpretation of the
'dst' side depends on the 'src' side (for example, when
creating a new unqualified remote ref, we use the same type
as the src ref).
This patch lets match_explicit return early when the src
side of the refspec is bogus. We still look at all of the
refspecs before aborting the push, though.
At the same time, we clean up the call signature, which
previously took an extra "errs" flag. This was pointless, as
we didn't act on that flag, but rather just passed it back
to the caller. Instead, we now use the more traditional
"return -1" to signal an error, and the caller aggregates
the error count.
This change fixes two bugs, as well:
- the early return avoids a segfault when passing a NULL
matched_src to guess_ref()
- the check for multiple sources pointing to a single dest
aborted if the "err" flag was set. Presumably the intent
was not to bother with the check if we had no
matched_src. However, since the err flag was passed in
from the caller, we might abort the check just because a
previous refspec had a problem, which doesn't make
sense.
In practice, this didn't matter, since due to the error
flag we end up aborting the push anyway.

It worked that way since commit 50f575fc (Tweak diff colors,
2006-06-22), but commit c1795bb0 (Unify whitespace checking, 2007-12-13)
changed it. This patch restores the old behaviour.
Besides Linus' arguments in the log message of 50f575fc, resetting color
before printing newline is also important to keep 'git add --patch'
happy. If the last line(s) of a file are removed, then that hunk will
end with a colored line. However, if the newline comes before the color
reset, then the diff output will have an additional line at the end
containing only the reset sequence. This causes trouble in
git-add--interactive.perl's parse_diff function, because @colored will
have one more element than @diff, and that last element will contain the
color reset. The elements of these arrays will then be copied to @hunk,
but only as many as the number of elements in @diff. As a result the
last color reset is lost and all subsequent terminal output will be
printed in color.

Now that we've made the loose SHA1 file reading more careful and
streamlined, we only use the old find_sha1_file() function for checking
whether a loose object file exists at all.
As such, the whole 'return stat information' part of it was just
pointless (nobody cares any more), and the naming of the function is not
really all that relevant either.
So simplify it to not do a 'stat()', but just an existence check (which
is what the callers want), and rename it to 'has_loose_object()' which
matches the use.

We used to do 'stat()+open()+mmap()+close()' to read the loose object
file data, which does work fine, but has a couple of problems:
- it unnecessarily walks the filename twice (at 'stat()' time and then
again to open it)
- NFS generally has open-close consistency guarantees, which means that
the initial 'stat()' was technically done outside of the normal
consistency rules.
So change it to do 'open()+fstat()+mmap()+close()' instead, which avoids
both these issues.

Instead of creating new temporary objects in the top-level git object
directory, create them in the same directory they will finally end up in
anyway. This avoids making the final atomic "rename to stable name"
operation be a cross-directory event, which makes it a lot easier for
various filesystems.
Several filesystems do things like change the inode number when moving
files across directories (or refuse to do it entirely).
In particular, it can also cause problems for NFS implementations that
change the filehandle of a file when it moves to a different directory,
like the old user-space NFS server did, and like the Linux knfsd still
does if you don't export your filesystems with 'no_subtree_check' or if
you export a filesystem that doesn't have stable inode numbers across
renames).
This change also obviously implies creating the object fan-out
subdirectory at tempfile creation time, rather than at the final
move_temp_to_file() time. Which actually accounts for most of the size
of the patch.

In git, all commits end in exactly one newline character. In svn, commits
end in zero or more newlines. Thus, when importing commits from svn into
git, git-svn always appends two extra newlines to ensure that the
git-svn-id: line is separated from the main commit message by at least one
blank line.
Combined with the terminating newline that's always present in svn commits
produced by git, you usually end up with two blank lines instead of one
between the commit message and git-svn-id: line, which is undesirable.
Instead, let's remove all trailing whitespace from the git commit on the way
through to svn.

If we are exporting a commit which has no parents we may be doing
it to a branch that already exists, causing fast-import to assume
the branch's current revision should be the sole parent of the
new commit. This can cause `git fast-export | git fast-import`
to produce an incorrect graph for:
A-------M----o------o refs/heads/master
/
B-+
In this graph A and B are initial commits (no parents) but if A was
output first to refs/heads/master and then B is output fast-import
would assume the graph was this instead:
A-------M----o------o refs/heads/master
\ /
+-B-+
Which would cause B, M, and all later commits to have a different
SHA-1, and obviously be quite a different graph.
Sending a reset command prior to B informs fast-import to clear
the implied parent of A, allowing B to remain an initial commit.

On Solaris it apparently fails to process input that doesn't end in a LF.
