Arrrrrrrrrrrrrrrrrrrgh.

Now, whose grep are we going to support?  Should we teach every
flag GNU grep supports that can take a parameter to the script?

Can we cheat and do something like this instead?

    git grep -B 6 -A 2 frotz -- arch/i386
    git grep -B 6 -A 2 frotz --others arch/i386

That is, things up to a known git-ls-files flag  or -- are
passed to grep and the rest is given to git-ls-files.
