git grep argument parser bug

In both ubuntu versions of git 1.9.1 and 2.7.0

    git grep '-test'
    git grep '--help'

Or any other expressions literal leading with a single dash or double
dash get interpreted as argument flags and not as search expressions.

What I expect is grep results for the literal strings "-test" and "--help"
What i get is git help output informing of wrong argument usage, or
accidentally turning on flags I didn't expect.

Work around; for afflicted users terminating argument parsing with `
-- ` works as it should.

    git grep -- '-test'

Confirmed on two Ubuntu [based] systems, Ubuntu Server 14.03 and
LinuxMint 17.3 [Cinnamon]

(Un)Quoting is done by shell and stripped out before "git" is
executed. We just don't see them.

    git grep -- '-test'

Or you can do "git grep -e --test". UNIX grep faces the same problem,
and also has -e to deal with it.
