To this:

Aha! That's what it was! Thanks!
At any rate, changing the test script's utterly nonspecific shebang
(that, I gather, essentially just said "this is a script, but you're on
your own to figure out what interpreter it wants"), and the backup
script's "#!/bin/sh" shebang both to a "#!/bin/bash" shebang solved the
problem quite nicely.
And late last night (actually, early this morning), after I'd left the
box with Gnome signed off and ExternalHD very deliberately unmounted,
the backup script worked perfectly.
