The key word is "somewhere".  The first somewhere that installs
a transient keymap in post-command-hook needs to get that keymap.
Currently it gets it from the symbol property of this-command.

The second somewhere is the place where it's already stashed by
set-transient-map in overriding-terminal-local-map.  That keymap
could be checked, but there is no need since it would be easier
just to use the KEEP-PRED arg.
