Yes, though I held back on writing tests, because I don't think we've
quite decided what the behavior _should_ be. Should we be
differentiating "chmod -x /bin/ls" from "chmod -x /bin"? Should we be
continuing alias lookup on EACCES? Should we print edit-distance
suggestions on EACCES?

I think the four cases from my previous email would be reasonable things
to test, but I wasn't sure what the expected outcomes should look like.
