Speaking of wanting things to work with the actual repository , one thing that I've been meaning to continue work on if I get the time is basically a 'show me any commit diff's that involve string s' (ie, the locations in which a change involving s occurs rather than just 'current file contains s (in exactly the same ways the previous version did). I'm extremely unlikely to actually produce anything based on that in the near future. But one thing that struck me that might be reasonably useful is some way of filtering the "context" that a string occurs in (is it in generic code context, in a string or in a comment). These are things that tend to be reasonably parametrisable by regular expressions (although escaping string delimiters within in strings makes completely correct behaviour tricky), so if git-grep itself were to be extended I'd prefer something that can be specified per search in a more generally usable way than something very C specific. Of course this is a quite difficult task as the actual diff may not contain enough lines to distinguish, eg, that it occurs within a longer comment. (As already disclaimed, I'm unlikely to actually get around to doing any of this work).
