   Because I wanted require to stay on top of the file, but I didn't want
   to put the rest of the git-grep stuff there.

Good point. Though, you can still "embed" the require form
directly into the defun. This is thing I have already seen in the
past. Dunno if it is a convention or a coding style but something
like:

(defun git-grep ()
 "Docstring"
 (interactive)
 (when (require 'grep nil t)
       here the rest
  ))

is doable too. Maybe the if-else form would be better though with
an else clause to (error "No grep package foud.").

Well just kidding, your patch is okay ;)
