feedback: do not list "." and ".." as possible <Tab><Tab> completions 

The single dot serves no purpose, as the user is already there.  And
the double dot is reached more easily by typing a second dot first.

And anyway, . and .. are not shown when the user does not type a dot
first, so why show them when the user types a single dot followed by
<Tab><Tab>?  Most likely the user wants to see actual dot files, so
just show those.

This fixes https://savannah.gnu.org/bugs/?58619.
