0f134f0267 Small optimizations to the grammar for window functions save about 120 bytes 
of space in the parser tables.

94809086e5 Use a separate bit on db->dbOptFlags to disable the xInverse optimization on

3de52e8fa0 Including the phrase EXCLUDE NO OTHERS in the frame-spec of a window function 
(which is the default setting for EXCLUDE) silently disables the xInverse
optimization.  This is a feature, but we will keep it undocumented for now
in case we later decide it is a bad idea.

check-ins by mistake, and so those check-ins are not fully functional.
