feature suggestion: c-X G

[ZVONA%MIT-OZ@MIT-MC.ARPA]

c-X G puts point at the beginning of the text it snarfs into the
buffer.  I often wish it would put it at the end.  Suppose that c-X X
saved an extra bit of state that said which end of the region point
was at when you save to the q-register.  Then c-X G would put you back
at that same end.
