Subject: [PATCH] Display commands with repeat-continue-only in
 describe-repeat-maps

* lisp/repeat.el (describe-repeat-maps): Display commands with the
property 'repeat-continue-only' used to continue the currently
active repeat-map (bug#74140).  Also use 'cl--map-keymap-recursively'
instead of 'map-keymap' to find more deep keybindings.

(cherry picked from commit f025c9df48f8ad5f1cb13c9adac2fc1fbeb81b79)
