Re: beginning-of-thing-pos, end-of-thing-pos

[Karl Fogel]

This sounds like a good idea to me.

You might want to call them "-point" instead of "-pos", as that seems
to be the most common convention for this sort of thing.  I did a
search of all symbols and "-point" was most common, followed by
"-pos", followed distantly by "-posn".  Also, "-point" avoids
confusion with the "position" objects returned by 'event-start' and
'event-end' and used by the 'posn-*' functions.
