We'll still need that placeholder in grep-find-template (and probably in 
grep-template, for consistency).

Regarding M-x grep, I would rather leave it alone for now, because 
otherwise, %s or not, that would call for renaming the variable 
grep-command, and grep-template is already taken.

Another option would be to perform the substitution with regexp in 
grep-default-command, and it's pretty hairy already.
