grep: avoid resolving revision names in --no-index case
We disallow the use of revisions with --no-index, but we don't actually check and complain until well after we've parsed the revisions. This is the cause of a few problems: 1. We shouldn't be calling get_sha1() at all when we aren't in a repository, as it might access the ref or object databases. For now, this should generally just return failure, but eventually it will become a BUG(). 2. When there's a "--" disambiguator and you're outside a repository, we'll complain early with "unable to resolve revision". But we can give a much more specific error. 3. When there isn't a "--" disambiguator, we still do the normal rev/path checks. This is silly, as we know we cannot have any revs with --no-index. Everything we see must be a path. Outside of a repository this doesn't matter (since we know it won't resolve), but inside one, we may complain unnecessarily if a filename happens to also match a refname. This patch skips the get_sha1() call entirely in the no-index case, and behaves as if it failed (with the exception of giving a better error message).
