Fixed a packaging issue.

0.4.0

New patchview mode with accompanying scripts. New grepdiff option --only-match. New filterdiff option --remove-timestamps. Assorted other fixes and improvements.

0.3.4

Some fixes for filterdiff and rediff. The splitdiff utility now has an option to write output to a subdirectory. Ranges can now be prefixed by a modifier ('x') to exclude spans instead of include them. Extended headers produced by git are now handled by filterdiff and interdiff.
