feedback for bad command prefix usage

Browse Source 
The old code to supply a list of directions if a prefix was followed
by a non-direction didn't work as intended anymore.  Add some more
precise feedback for gGF mis-use and comment out some code that never
gets executed.

A number_pad user can get a complaint about 'G' when using '5' followed
by a non-directional command.  Too bad for them.

Supersedes pull request #803
