Hmm. PCRE is probably wide-spread enough that it could be an option.
What's PCRE performance like? I'd hate to make "git grep" slower, and it would be stupid and confusing to use two different regex libraries..
Maybe somebody could test - afaik, PCRE has a regex-compatible (from a API standpoint, not from a regex standpoint!) wrapper thing, and it might be interesting to hear if doing "git grep" is slower or faster..
(I realize that the performance thing depends heavily on the patterns and the working set they are used on, but I guess _I_ personally only care about fairly simple patterns on the kernel ;)
