Ah, someone who hasn't experienced the... experience of working on a project that does very esoteric autotools magic.

I will agree that in a sane project setup you don't need to search through all files including build artifacts ignored by git.

Even in an insane setup you generally don't want to search both at once. I find the pattern of first grepping non-ignored files and then cd-ing into my build directory or whatever and rerunning more helpful anyway.
