New parser request: git log -p --format=fuller

[jpluscplusm]

The existing git-log parser doesn't know what to do with log output that includes an inline patch - generated with the -p flag.

This stream of data would be really useful when JSONified, especially combined with the fuller format, as that could then represent a near-complete record of a repo's history as structured data! (Modulo binary files in the patch; I've no idea what jc could/should do with them ... )
