I'm wondering why we have to use last_point_position.
It seems to be asking for problems because it is delimited by command
processing, whereas the undo records are delimited by undo-boundary:
there is a correlation between the two, but no equivalence.

I.e. I suggest we introduce last_undo_boundary_pos and use it in place
of last_point_position in undo.c.
It'd be set to PT in Fundo_boundary (which could/should also set
last_undo_buffer).

WDYT?
