Indeed -- I just got around to changing this (been an odd week)...
combining it with a hint from greg:

dotglob is already activated, nullglob is not.  I thought about it
if nullblob is unset, then I'll always have 1 element in the array --
so I don't have to worry about coding for an 'unset' value.

So all I need do is test the first entry:

   local -a entries=("$1"/*)
   [[ ${entries[0]} == $1/* ]] && return 0

--- the $1 doesn't need quotes in [[]] and '*' won't expand or
am missing something?  Thanks for the tip Pierre, I often
don't see forests because of all the trees...
