HyControl uses post-command-hook to persist a prefix-argument value across
commands and to continually display a help message in the minibuffer until
exit.

​​Just curious, why does set-transient-map use pre-command-hook instead of
post-command-hook​ to test whether or not to keep the transient-map
enabled?  This prevents the test from using the results of the most recent
key binding run.
