Tty and Shell refuse a directory: not a shell

A directory passes access(X_OK), so Tty /etc made a pane whose shell
exited 127 and Shell /etc was taken. The shell lookup now refuses a
directory, and both say "not a shell: /etc is a directory" (Tty and
Shell share one refusal, host_io.Shell.refusal). shellset's golden takes
the shared wording (re-recorded by name).
