* eval.c (rb_thread_restore_context): save current value of
lastline and lastmatch in the thread struct for later restore.
* eval.c (rb_thread_save_context): restore lastline and lastmatch.
* numeric.c (flo_to_s): should handle negative float value.
* class.c (rb_include_module): should check whole ancestors to
avoid duplicate module inclusion.
* string.c (trnext): should check backslash before updating "now"
position.
