Don't do that ;) test_must_fail is meant for testing (git) commands such that a "failure return code" is marked as "success", whereas a failure to run the command is still capturd and marked as a failed test. For non-git commands like grep sed etc. which we do not perform tests *on* (but only *with*), the simple negator "!" is fine and preferable.
