grep -O: allow optional argument specifying the pager (or editor)

Suppose you want to edit all files that contain a specific search term.
Of course, you can do something totally trivial such as

	git grep -z -e <term> | xargs -0r vi +/<term>

but maybe you are happy that the same will be achieved by

	git grep -Ovi <term>

now.
