[Extension] Dirty hack of 'shelve' and 'unshelve' command

[Michael Ellerman]

Hey again,

Here's a couple of patches that add an option to diff "--hunks" which is more 
aggresive about splitting hunks. It basically just allows context to overlap, 
so if your changes have 3 lines between them they'll be split.

Any finer granularity is best achieved by allowing hunks to be edited, I 
think. So I'm not sure this patch is really worth the trouble, but here it is 
anyway for people to try.

There's two patches against bzr, one just imports difflib.py, the second hacks 
it and bzr to do the --hunks stuff.

The third patch is trivial against shelf.py to add use of the --hunk option.

night!
