Rev-parse understands that a "--" may separate revisions and filenames, and that anything after the "--" is taken as-is. However, it does not understand that anything before the token must be a revision (which is the usual rule implemented by the setup_revisions parser). Since rev-parse prefers revisions to files when parsing before the "--", we end up with the correct result (if such an argument is a revision, we parse it as one, and if it is not, it is an error either way). However, we misdiagnose the errors: $ git rev-parse foobar -- >/dev/null fatal: ambiguous argument 'foobar': unknown revision or path not in the working tree. Use '--' to separate paths from revisions, like this: 'git <command> [<revision>...] -- [<file>...]' $ >foobar $ git rev-parse foobar -- >/dev/null fatal: bad flag '--' used after filename In both cases, we should know that the real error is that "foobar" is meant to be a revision, but could not be resolved.
