I guess you're right, in that neither is exactly the same as non-git,
and so it's impossible to objectively quantify how one is "closer". My
general feeling though is that grep rooted at the current directory is
more similar because grep -r does exist and is common enough that the
layman isn't too surprised at git's default behavior. Git grep with
--full-tree though, has no analogue in non-git grep.
