parent directory.
If you wish to inhibit this behaviour entirely, set the tt(path-completion)
style (see below) to `false'.

top-level pathnames can not be listed or generated with glob patterns

with this problem). It can also be used for directories for which one

The pattern form can be used to add a certain `magic' entry
to all directories on a particular file system.
