It's needed for getting there after a redo.

Any `record-point' would simply have to preserve the symmetry of
UB RPB buffer-changes RPA UB RPB buffer-changes RPA UB
where UB is the undo-boundary, RPB and RPA the `record-point's before
and after the buffer-changes, and the buffer-changes would not contain
any undo-boundaries or point-recordings.

We could remove certain text-properties from undo-lists (mine are
usually full of 'fontified properties in deleted text).
