grep: ignore --recurse-submodules if --no-index is given
Since grep learned to recurse into submodules in 0281e487fd (grep: optionally recurse into submodules, 2016-12-16), using --recurse-submodules along with --no-index makes Git die(). This is unfortunate because if submodule.recurse is set in a user's ~/.gitconfig, invoking `git grep --no-index` either inside or outside a Git repository results in fatal: option not supported with --recurse-submodules Let's allow using these options together, so that setting submodule.recurse globally does not prevent using `git grep --no-index`. Using `--recurse-submodules` should not have any effect if `--no-index` is used inside a repository, as Git will recurse into the checked out submodule directories just like into regular directories.
