files: disallow tabbing when in restricted mode

Tabbing can list all files in the given directory, but restricted mode
is supposed to prevent the user from any access to the filesystem...

This fixes https://savannah.gnu.org/bugs/?58632.

Bug existed (in this form) since version 1.3.4, commit f7b5d930.
