The --color flag wasn't introduced until git 1.6.3. Prior to that
version, `git grep --color` just produces a fatal error, as it is
an unsupported option. Since this is just pretty output and is not
critical to execution, we can simply omit the option if the version
of git we are running on doesn't support it.

Users can now use 'repo grep' to search all projects, rather than
'repo forall -c git grep'. Its not only shorter to type, but it
also filters results better by highlighting which projects matched
in the client workspace.
