bundled/jinja2/custom_fixers/fix_broken_reraising.py @ 22de90ef33ed 

Add identifiers to ReviewChangeset's and ReviewSignoff's.

The identifier of a rcset/rsignoff is the filename it was saved as, which is
the hash of its contents.

This will be useful when we want to add replies to comments/signoffs.

CLI support for this feature has also been added (using --verbose and --debug
flags with 'hg review [-r REV]'), as well as some simple unit tests.
