deactivated as part of the command loop. The text *did* move when I

Ok, this appears to be a regression in CVS Emacs. Emacs 23.2.1 does indent the region properly, as you say.
Region deactivation is the default behaviour in Emacs for all functions I can think of. It would be surprising if it did something else. You can reactivate the region with C-xC-x.
