I should have mentioned this bug won't show up if emacs is running in a
tty. The bug
stems from the subtle difference between C-SPC and C-@ input events on
graphical
terminals. On a tty, C-SPC and C-@ become the same thing before they get
to emacs.

You can start an emacs -nw inside the term. Then pressing C-SPC should
result in a "Mark set" in the inner emacs's echo area.
