Sorry for being unclear; no, the $Date$ line is the only change that shows up. I removed the surrounding context because I didn't want to publish them.

On another machine, there is another file that exhibits the same problem.

But then I need to check it in again, and I'd like to avoid that, if possible.

Is it possible to have a filter run on "commit" instead of "add"? (Or is "commit" just moving changes from the index to the repository, making that impossible?)

It seems to be triggered by using my date script and doing

   git add file
   git commit file
   git reset --hard file

the last command gives me a local copy with the keyword expanded, but marked dirty.

Is it possible to have "git add" expand the keyword (both the Git-internal "ident", i.e "$Id$", and my "$Date$")? Would duplicating the "clean" filter as a "smudge" one accomplish that?
