I updated and confirm that C-M-mouse-1 now selects a rectangle also when
transient-mark-mode is disabled, and also that I don't see the bad
side-effects I saw with my patch.  Thanks!

I'm not sure what you're referring to here; as noted, your patch doesn't
have the bad side-effects I observed with my patch.  And I don't recall
seeing any such behavior when selecting a region with mouse-1 help down
(I assume that's what you mean by linear text selection with the mouse),
before your patch and don't see it with it either.

Unless I'm misunderstanding what you mean, I see no problems with
selection (rectangular or linear) with the mouse now.
