This would be so much more convenient if git-grep supported it natively:

$ git grep -n 'if \(0\)' | perl -pe's/([^:]+):([^:]+).*/`git blame -L
$2,$2 $1`/se'
d18f76dc (Ævar Arnfjörð Bjarmason 2010-08-17 09:24:38 +0000 2278)   if (0)
65648283 (David Brown 2007-12-25 19:56:29 -0800 433) if (0) {

I.e. with all the coloring/pager interaction. Some Googling around
reveals people piping things to git-blame like that, but has anyone
made a stab at a smarter implementation (that would know to blame the
whole file if it had lots of hits etc..).

Don't know if I have time myself, but I'd be very pleased if someone
hacked that up.

Errr... 'git blame -L' supports regexps as starting and ending point,
see git-blame(1) manpage:

    git blame -L '/^sub hello {/,/^}$/' foo

It does not color matching, though...
