[PATCH] allocate origline by ztrdup(), not by dupstring()

["Jun T." <takimoto-j@kba.biglobe.ne.jp>]

Currently, domenuselect() allocates origline in heap by dupstring(),
but if menuselect() is called directly as a widget then the heap has
already been freed (and may have been re-used for other variables).
