[PATCH] Add "git grep" helper
Very convenient shorthand for git-ls-files [file-patterns] | xargs grep <pattern> which I tend to do all the time. Yes, it's trivial, but it's really nice. I can do git grep '\<some_variable\>' arch/i386 include/asm-i386 and it does exactly what you'd think it does. And since it just uses the normal git-ls-files file patterns, you can do things like git grep something 'include/*.h' and it will search all header files under the include/ subdirectory.
