Another suggestion for improvement to this system (which is really
handy by the way) would be to skip diffs that are empty.
For example, suppose I create foo.orig file but eventually decide not
to edit foo (or revert my changes). It would be nice if pkgdiff would
recognize that the diff is empty and not bother creating a patch.
Then developers don't have to worry about either deleting redundant
*.orig files or having empty patches.
I'm not enough of a perl wizard to know how to change pkgdiff, but
there must be a simple means of checking whether the $diff variable is
empty and skipping the rest of the processing (e.g., adding $NetBSD$,
