In macOS there is a file,
/usr/sbin/weakpass_editthat is a symlink to a directory that is only readable byroot. Our REPL shell completion attempts to callisfile()when entering the shell mode and pressingw, throwing an ugly error into the REPL.This PR fixes the root cause (skipping files that fail the
isfile()condition) and adds a test that synthesizes an analogous condition.
