2012-10-15) changed match_attr structure but it did not update
DEBUG_ATTR-specific code. This fixes it.

94bc671 (Add directory pattern matching to attributes - 2012-12-08)
uses find_basename() to calculate the length of directory part in
prepare_attr_stack. This function expects the directory without the
trailing slash (as "origin" field in match_attr struct is without the
trailing slash). find_basename() includes the trailing slash and
confuses push/pop algorithm.
Consider path = "abc/def" and the push down code:
while (1) {
len = strlen(attr_stack->origin);
if (dirlen <= len)
break;
cp = memchr(path + len + 1, '/', dirlen - len - 1);
if (!cp)
cp = path + dirlen;
dirlen is 4, not 3, without this patch. So when attr_stack->origin is
"abc", it'll miss the exit condition because 4 <= 3 is wrong. It'll
then try to push "abc/" down the attr stack (because "cp" would be
NULL). So we have both "abc" and "abc/" in the stack.
Next time when "abc/ghi" is checked, "abc/" is popped out because of
the off-by-one dirlen, only to be pushed back in again by the above
code. This repeats for all files in the same directory. Which means
at least one failed open syscall per file, or more if .gitattributes
exists.
This is the perf result with 10 runs on git.git:

Since 90e1818f9a (git-rebase: add keep_empty flag, 2012-04-20)
'git rebase --preserve-merges' fails to preserve empty merge commits
unless --keep-empty is also specified. Merge commits should be
preserved in order to preserve the structure of the rebased graph,
even if the merge commit does not introduce changes to the parent.
Teach rebase not to drop merge commits only because they are empty.
A special case which is not handled by this change is for a merge commit
whose parents are now the same commit because all the previous different
parents have been dropped as a result of this rebase or some previous
operation.

(1) Only print out the names of the files and directories that got
actually deleted. Also do not mention that we are not removing
directories when the user did not ask us to do so with '-d'.
(2) Show ignore message for skipped untracked git repositories.
Consider the following repo layout:
test.git/
|-- tracked_dir/
| |-- some_tracked_file
| |-- some_untracked_file
|-- tracked_file
|-- untracked_file
|-- untracked_foo/
| |-- bar/
| | |-- bar.txt
| |-- emptydir/
| |-- frotz.git/
| |-- frotz.tx
|-- untracked_some.git/
|-- some.txt
Suppose the user issues 'git clean -fd' from the test.git directory.
When -d option is used and untracked directory 'foo' contains a
subdirectory 'frotz.git' that is managed by a different git repository
therefore it will not be removed.
$ git clean -fd
Removing tracked_dir/some_untracked_file
Removing untracked_file
Removing untracked_foo/
Removing untracked_some.git/
The message displayed to the user is slightly misleading. The foo/
directory has not been removed because of foo/frotz.git still exists.
On the other hand the subdirectories 'bar' and 'emptydir' have been
deleted but they're not mentioned anywhere. Also, untracked_some.git
has not been removed either.
This behaviour is the result of the way the deletion of untracked
directories are reported. In the current implementation they are
deleted recursively but only the name of the top most directory is
printed out. The calling function does not know about any
subdirectories that could not be removed during the recursion.
Improve the way the deleted directories are reported back to
the user:
(1) Create a recursive delete function 'remove_dirs' in builtin/clean.c
to run in both dry_run and delete modes with the delete logic as
follows:
(a) Check if the current directory to be deleted is an untracked
git repository. If it is and --force --force option is not set
do not touch this directory, print ignore message, set dir_gone
flag to false for the caller and return.
(b) Otherwise for each item in current directory:
(i) If current directory cannot be accessed, print warning,
set dir_gone flag to false and return.
(ii) If the item is a subdirectory recurse into it,
check for the returned value of the dir_gone flag.
If the subdirectory is gone, add the name of the deleted
directory to a list of successfully removed items 'dels'.
Else set the dir_gone flag as the current directory
cannot be removed because we have at least one subdirectory
hanging around.
(iii) If it is a file try to remove it. If success add the
file name to the 'dels' list, else print error and set
dir_gone flag to false.
(c) After we finished deleting all items in the current directory and
the dir_gone flag is still true, remove the directory itself.
If failed set the dir_gone flag to false.
(d) If the current directory cannot be deleted because the dir_gone flag
has been set to false, print out all the successfully deleted items
for this directory from the 'dels' list.
(e) We're done with the current directory, return.
(2) Modify the cmd_clean() function to:
(a) call the recursive delete function 'remove_dirs()' for each
topmost directory it wants to remove
(b) check for the returned value of dir_gone flag. If it's true
print the name of the directory as being removed.
Consider the output of the improved version:
$ git clean -fd
Removing tracked_dir/some_untracked_file
Removing untracked_file
Skipping repository untracked_foo/frotz.git
Removing untracked_foo/bar
Removing untracked_foo/emptydir
Skipping repository untracked_some.git/
Now it displays only the file and directory names that got actually
deleted and shows the name of the untracked git repositories it ignored.

The --separate-git-dir option was introduced to make it simple to put
the git directory somewhere outside the worktree, for example when
cloning a repository for use as a submodule.
It was not intended for use when creating a bare repository. In that
case there is no worktree and it is more natural to directly clone the
repository and create a .git file as separate steps:
git clone --bare /path/to/repo.git bar.git
printf 'gitdir: bar.git\n' >foo.git
Forbid the combination, making the command easier to explain.

Rely on the upstream filetype.vim instead of duplicating its rules in
git's instructions for syntax highlighting support on pre-7.2 vim
versions.
The result is a shorter contrib/vim/README. More importantly, it lets
us punt on maintenance of the autocmd rules.
So now when we fix the upstream gitsendemail rule in light of commit
eed6ca7, new git users stuck on old vim reading contrib/vim/README can
automagically get the fix without any further changes needed to git.
Once the world has moved on to vim 7.2+ completely, we can get rid of
these instructions, but for now if they are this simple it's
effortless to keep them.
