[Orgmode] FR: keystroke to cancel prefix sub-keymap

Suppose that I have a sub-keymap for custom agenda commands with
prefix 's', i.e. shortcuts 's1', 's2', 's3' and so on.  I might invoke
org-agenda, press 's', then change my mind and want to use another
custom command instead.  Currently, the only way of doing this would
be to press something like 'q' or C-g, then reinvoke org-agenda.  It
would be nice instead if there was a keystroke which simply returned
you to the first *Agenda Commands* buffer.  The following patch
demonstrates the required behaviour, but as you can see, is not a
particularly clean way of doing it.
