No, sorry.

At least it does on this True 64 Unix here.

For users one could test $+userdirs[<name>].

That was caused by _files which has to put backslashes before the colons
in the pattern it gets and later has to double the number of
backslashes.  There I forgot the `g' before the `s' modifier.

Hm.  We should then at least do something like

  eval 'tmp1=( $~tmp1 )' 2>/dev/null || ...

where the `...' either returns with a non-zero value or uses _message to
say that the pattern was badly formed.  Or both.  Or make it selectable
with an option to _path_files.  Or something.
