I've created a little python script to produce patches from log
messages - i.e.:
patchmaker "Bug 123"

But it breaks down when the revision is the very first revision.
Usually it makes diffs like this:
cmd = "cvs -q diff -u -r %s -r %s %s" % (self.prevrev, self.rev, fobj)

cvs -q diff -u -r -r somefile

But there's no previous rev to the first rev - and you can't do
cvs -q diff -u -r 0 -r 1.1 somefile

Help appreciated!
how about when self.prevrev==0
cvs diff -u --new-file -D"1 Jan 1970" -r1.1 somefile

The trick is, the file was (probably) not put into CVS with a date before "1 Jan 1970".
