'$Format:' is processed when creating an archive. It's mentioned with
export-subst only under the heading "create archive". So, that is as

"git replaces $Id$... upon checkout.  Any byte sequence that begins with
$Id: and ends with $ in the worktree file is replaced with $Id$ upon

Now, the there are two problems after you add $Id$ and check-in (commit):

- commit does not check out, i.e. your work-tree copy is not updated
with expanded $Id$
- Not even "git checkout thatFile" updates your work-tree copy.

The first one could be considered OK, but at least the second one seems
to be a bug. Together they create the following problem: Say, you've
corrected that problem (rm that file and checkout) and then update your
