	Here's an example program that will read a git style diff and print  
out all of the renames.  If there are any reliability problems with  
it, they'd be fatal to mercurial:

#########################################

#!/usr/bin/env python

import sys
import mercurial.patch

f=open(sys.argv[1])
num, patches=mercurial.patch.readgitpatch(f)
f.close()

for patch in [p for p in patches if p.op == 'RENAME']:
     print "%s -> %s" % (patch.oldpath, patch.path)

#########################################

	I made a test patch by exporting a patch that contained a rename.  It  
sounds like you may already have such a thing, though.
