Title: Formula for 'The Silver Searcher', a faster 'ack'

The Silver Searcher (ag) is a faster, smarter, replacement for ack (and grep), written in C.
The released versions of ag use getline and strndup, which are only present in OS X 10.7+,
Users of OS X 10.6 and below will need to use --devel --HEAD until my patches make it into an upstream release.
