autodescribe vs detection

Browse Source 
Temporary map views for detection or #terrain allow moving the cursor
around to get the brief location description provided by getpos's
autodescribe feature and were doing so by forcing the 'autodescribe'
option to True, then leaving it that way.  Save the option value prior
to such operations and restore it after instead of leaving it changed.
