Ah, yes, of course!  Thanks for that most important correction!

(not having anything within my work directories, since the objects in my
pkgsrc tree are actually all symlinks, didn't help me to see that they
would still have been decended into!)

Too bad (for simple name-compare-only "find" expressions anyway) that
directory files don't contain a flag bit which would identify files
which are themselves sub-directories.  Then maybe the "find" example
could have a run time that was a bit closer to the shell glob example.
