[PATCH 3/4] grep docs: --cached and <tree>... are incompatible

[Mark Lodato <lodatom@gmail.com>]

In the synopsis for git-grep(1), show that --cached and <tree>... cannot
be used together.

One downside to this change is that having --cached makes it prominent, which
is good since it's a very common option.  However, I think accuracy is more
important here.
