Don't include child directories of $PATH in completions

Directories are completed like commands, because of implicit cd.
However, directories found inside $PATH entries should not be completed,
as implicit cd doesn't work there. Similarly, directories should not be
completed after the `command` builtin.

Fixes #1695.
