From d4d28a2beed3aca3510b39cc8cc55df4852d96ef Mon Sep 17 00:00:00 2001

Subject: Remove multi-purpose Options.mlist_targetting.

The option is now just a boolean option, and whether we're
actively targetting with the mlist is stored in
crawl_state.mlist_targetting.

Also remove some duplication of mlist logic from direction().
