committer: Dmitry Antipov <address@hidden>
branch nick: trunk
timestamp: Fri 2012-08-31 14:53:19 +0400
message:
  Remove mark_ttys function and fix tty_display_info initialization.
  * lisp.h (mark_ttys): Remove prototype.
  * alloc.c (Fgarbage_collect): Remove redundant (and the only) call
  to mark_ttys because all possible values of 'top_frame' slot are
  the frames which are reachable from Vframe_list.
  * term.c (mark_ttys): Remove.
  (init_tty): Safely initialize 'top_frame' slot with Qnil.
