Subject: Allow numbers as second input event (#8471)

* Make sure pending key list is empty when count handling

This will allow using numbers as second key event.

* count handling; add an exception for 'g'

* Lookup the key event before considering a number as count

* Avoid the allocation of another vec for the pending keys
