Currently, I've got a perl script that modifies the Id line in a smudge filter:
[filter "ident-line"]
  smudge = /usr/local/bin/githook_ident-filter.pl %f

The problem I've noticed with smudge filters is that it leaves the
repo dirty. How do I fix this? I am basically trying to replicate the
behavior of CVS or SVN $Id$ line here.

It somewhat smells fishy to have only smudge filter defined without
a corresponding clean filter, doesn't it?
