Actually, it wasn't! The transient map disappears the first time any key
is hit that isn't in the map itself. What I wanted was to rewire "q",
and nothing but "q", until the first time that "q" is hit. I can
probably still get what I want by fooling with the KEEP-PRED argument to
`set-transient-map', but it's not the no-brainer I thought it was.
