That's unnecessarily complex.
why not simply: entries=("$1"/*) ?

Indeed -- I just got around to changing this (been an odd week)...
combining it with a hint from greg:
You need to activate nullglob and dotglob first, but yes, that would be
the way I'd recommend.

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...
