Joerg Wunsch 3f0aecd3b5 Fix two minor oddities introduced by my yesterday's patches:
. preserve a multi-char sequence in a small static buffer inside
  pccngetc(), so it won't be clobbered later (used to happen when
  breaking into DDB user Ctrl-Alt-ESC), and

. simplify the ``keystroke is present'' determination in sgetc(), thus
  making pccncheck() actually working without waiting for a keystroke.
