Refactor ui-options.c so that different options sets always go in different pref file blocks (previously keymaps could be saved in both the options block and a keymap block).  Clean up output in prefs.c a bit.
Allow loading/saving of autoinscription preferences to pref file.
Add a note when you hit 'i' with no inventory, instead of doing nothing.
Refactor teleport_player_level() to ensure it never misbehaves.  I'm not sure if it could before but this version is a lot easier to follow.
Make sure down stairs from the town with force_descent never go beyond MAX_DEPTH-1.
