From: Arnaldo Carvalho de Melo <acme@redhat.com>
Sometimes we're in an outer code, like the main hists browser popup menu and the user follows a suggestion about using some hotkey, and that hotkey is really handled by hists_browser__run(), so allow for calling it with that hotkey, making it handle it instead of waiting for the user to press one.
