histedit: replace @addhisteditaction with @action

@action supports verbs, messages, priority, and internal

messages should be translated.
internal means the action should not be listed.

geteditcomment will construct the verbs list based on
@actions (prefering priority over non priority, otherwise
favoring verbs with short forms over verbs without).

  $ cd repo
