I've been looking at a method to tell whether just one file in a patch 
needs refreshing (to use as the last check in files_may_have_changed) 
and would like to use one of the commands (filterdiff) from patchutils

<http://freshmeat.net/projects/patchutils/>

to extract the patch for the file in question from the patch file so 
that it can be used to modify a copy of the file for comparison with the 
next version of the file above it in the series.  This would have the 
consequence of making quilt dependent on patchutils.  Would this be 
acceptable?
