Before the --, always attempt ref completion. This helps with
entering the <treeish> arguments to git-grep. As a bonus, you can
work around git-grep's current lack of --all by hitting M-*, ugly as
the resulting command line may be.
Strictly speaking, completing the regular expression argument (or
option argument) makes no sense. However, we cannot prevent _all_
completion (it will fall back to filenames), so we dispense with any
additional complication to detect whether the user still has to enter
a regular expression.
