Bug in git-cvsexportcommit: can't commit files which have been removed from CVS

Hi,

I think I've discovered a bug in git-cvsexportcommit: where a file has been removed from a CVS repository, it linger in the Attic and CVS perversely reports them as 'no file X' with status 'Up-to-date'. git-cvsexportcommit then prevents files from being added with the same name.

I have a patch against the current version of git's repository which seems to
fix the problem.  This is actually three commits:
 - the fix,
 - an extension to t9200-git-cvsexportcommit.sh to test the fix
 - EOL whitespace-removal

I'm hesitant to send all three as separate emails, even though the SubmittingPatches document seems to imply I should - should I squash them into one commit?

Anyway - to replicate the issue, create a CVS repository, add a file "x", then remove it.

Then create a git repository tracking this CVS repository using git-cvsimport. Pull the changes from CVS, then try adding a file "x", and exporting it back to CVS. When I do that I get this error:

  File x is already known in your CVS checkout -- perhaps it has
  been added by another user. Or this may indicate that it exists on a
  different branch. If this is the case, use -f to force the merge.
  Status was: Up-to-date
  Exiting: your CVS tree is not clean for this merge. at
  /usr/lib/git-core/git-cvsexportcommit line 275.

When comitting, I also sometimes get warnings like this:

  Huh? Status reported for unexpected file 'no file y'

These seem to be ignorable, but I think they also result from the above issue.

Cheers,

Nick
