Here's a modification of the shell function zls to do two things: it
uses Phil's -H option to assign to an assoc array for clarity, and it
handles the -t option, together with -u and -c, using Sven's O
glob qualifier. I think the way I got it to reorder an existing
argument list by time, as ls does with -t, works even when there are
funny characters in the file name. I should have done that to reorder
the list by name without -t, but I didn't have the heart.
