[PATCH] Added an option to cvsimport to specify email domain

["David Kågedal" <davidk@lysator.liu.se>]

The authorship info in commits created by git-cvsimport-script
only contains the username of the CVS committer.  This patch
adds a flag -e <domain> to git-cvsimport-script that makes it
possible to specify an email domain that is added to all email
addresses in the commit "author" and "committer" fields.

---
I have stopped using cvsimport, because cvsps seems to produce bad
output on the repository I'm using it with, but I had already prepared
this patch.
