This might be confusing, since overriding-local-map takes precedence
over the temporary map.

The reason I think "transient" is a good term to use is that we already
use that word in Emacs in `transient-mode-map' to mean the same sort of
behavior: a mode of operation which features disappears after doing
something, returning you to the previous behavior.  (We also use the
word "electric" similarly, but that is a lot more cryptic.)
