You need grep-find-template, not grep-find-command.

Yes, it's a mess. Auto-computed custom variable values don't make much 
sense to me either, but maybe the idea is if you want to change the 
program to use as 'find', it'll likely have a slightly different syntax 
(not in your case, though), and grep-compute-defaults might fail to 
work, so you're better off customizing the end values.

Probably.

It's the other way around: grep-compute-defaults sets grep-find-command 
using the value of find-program.
