No, it's a normal Emacs "shift-selection" feature: any cursor motion
command (C-a in this case) typed with the Shift key held will select
the text it moves across.  You can see it in *scratch* in "emacs -Q",
even.

No, I think it's because in message-mode C-a is bound to
message-beginning-of-line, and that doesn't have "^" in its
interactive spec, like beginning-of-line does.
