Before even calling this, all callers have done a "has_sha1_file(sha1)"
or "has_loose_object(sha1)" check, so there is no point in doing a
second check.
If something races with us on object creation, we handle that in the
final link() that moves it to the right place.

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.

In some cases, we produce a diffstat line even though no
lines have changed (e.g., because of an exact rename). In
this case, there is no +/- "graph" after the number of
changed lines. However, we output the space separator
unconditionally, meaning that these lines contained a
trailing space character.
This isn't a huge problem, but in cleaning up the output we
are able to eliminate some trailing whitespace from a test
vector.

All of these violations are necessary parts of the tests
(which are generally checking the behavior of trailing
whitespace, or contain diff fragments with empty lines).
Our solution is two-fold:
1. Process input with whitespace problems using tr. This
has the added bonus that it becomes very obvious where
the bogus whitespace is intended to go.
2. Move large diff fragments into their own supplemental
files. This gets rid of the whitespace problem, since
supplemental files are not checked, and it also makes
the test script a bit easier to read.

The test did "reset --hard" (where the HEAD commit has an empty
blob at path "empty") followed by "> empty", expecting that
the index does not notice the file _changed_ since git wrote
it out upon "reset" if the redirection is done quickly enough.
There was no need to do the emptying, and it gave a wrong result
if "reset --hard" happened on time T and then ">empty" happened on
the next second T+1. This fixes it.

Suppose the "Unstaged Changes" pane contains a list of files, and one of
them is selected (i.e., that diff is currently being displayed). If one
clicks on the icon to stage the change, git-gui clears the diff and one
has to click on another filename to see the next diff in the list.
This patch changes that behaviour. If one clicks on the icon to stage
(or unstage) the file whose diff is being displayed, git-gui will move
on to the next filename in the list and display that diff instead of a
blank diff pane. If the selected file was at the end of the list, the
diff pane will display the previous diff instead; if the selected file
was the only one listed, the diff pane will become blank.
If no diff is currently being displayed, this patch changes nothing.

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.

The behaviour of "sed" on an incomplete line is unspecified by POSIX, and
On Solaris it apparently fails to process input that doesn't end in a LF.
Consequently constructs like
re=$(printf '%s' foo | sed -e 's/bar/BAR/g' $)
cause re to be set to the empty string. Such a construct is used in
git-submodule.sh.
Because the LF at the end of command output are stripped away by the
command substitution, it is a safe and sane change to add a LF at the end
of the printf format specifier.
