MSVC complained that they might be used uninitialized. In some cases,
this might have been possible.
XRogue already has initializations for all these variables.
new_level() redraws the whole screen, including the message line, so if
msg() has just been called, the message will likely not last long
enough to be noticed. These cases have been changed so that msg() is
called after new_level().
If a fall through a trapdoor is fatal, "You fall into a trap!" is no
longer printed, but the tombstone should make things clear.
In both games, command() loops and calls the action function twice for
each command: once to schedule it by setting player.t_action and
player.t_no_move, and again, to actually do it, once player.t_no_move
has been reduced to 0. Each loop decremented count, so repeated
commands were only repeated half the number of times the player typed.
count is now decremented only when ch has been set to the repeated
command.
