"git grep" only searches tracked files by default, so to get correct behaviour, you will need to create an alias (I don't think there's a way to change the default). It also only works on Git repos; having to think before choosing between "git grep" and "ack" just adds unnecessary mental context switching. Personally, I prefer ack's output, which puts the file name on a separate line, and includes line numbers by default. Together with -C you get a much more readable output. Mostly I end up just using Sublime Text's built-in file search, which is like ack, but has a generous -C setting enabled by default, and supports replacing.
