Teach fmt-patch to write individual files.
When called with "--stdout", it still writes to standard output. Notable differences to git-format-patch: - since fmt-patch uses the standardized logging machinery, it is no longer "From nobody", but "From <commit_sha1>", - the empty lines before and after the "---" just before the diffstat are no longer there, - git-format-patch outputs the commit_sha1 just before the first diff, which fmt-patch does not, - the file names are no longer output to stdout, but to stderr (since stdout is freopen()ed all the time), and - "git fmt-patch HEAD^" does not work as expected: it outputs *all* commits reachable from HEAD^! The last one is possibly a showstopper. At least I used to call that command quite often...
