Okay, it's not as serious as I first thought, but there is still a
problem.

The issue is as follows.  When applying patches, my perl script effectively
does:

patch -p1 < patch
git add list-of-files-which-patch-added
git rm list-of-files-which-patch-removed
echo commit-message | git commit -F - -- list-of-files-added-and-changed

For 3834/1 (2172590e3aea712a4da90ac4eb6ca88f19a4ebea) which only removed
files, "list-of-files-added-and-changed" was empty, so it committed
_everything_.

However, one might ask why don't I include the list of deleted files
there.  Well, if I do, I get the following from my script and from
git:

Yes, git refuses to commit because I specified files which I wanted to be
committed but were deleted.  It seems that if I _don't_ specify these
files, they aren't committed in any case, unless I specify no files.

git bug I'd say - no way to specify a list of files added, changed _and_
_removed_ to be committed.
