PatR 88c8e92e76 debugpline() fix
Something which occurred to me when looking at the magic whistle code.
It's behavior can vary depending upon whether pline()/You()/&c has
been called and that is detected by checking whether pline() has reset
iflags.last_msg.  Change the debugpline() mechanism to prevent it from
interfering with that.
