Thanks for the explanation.  I see what's going on now.

Perhaps it would have been more useful for me to have given the
non-cut-down version of what I encountered: I had recorded a keyboard
macro, and then applied it to the lines in the region using `C-x C-k r'.
Despite many buffer modifications, the mark remained active.  This
struck me as counter-intuitive behaviour from a user level.

I wouldn't claim this is a huge problem, but if it could be fixed, I
think emacs' behaviour would be less surprising in this situation.
