pull request #811 - getpos help during ";"

Pull request from entrez:  context-sensitive help.  During the
quick farlook command (aka #glance), if the player types "?" to
ask for help don't show "prompt for 'more info'" among the actions
performed for response ".".  (":" still mentions that because it
does show 'more info', if some is available, when using ";".)

Closes #811
