blessed.diff fixes a bug whereby blessed weapons can be sold to the temple
whether or not the player knows them to be blessed. It does this by using
object_flags_known() rather than object_flags() to grab the appropriate flag.

mainchoice.diff creates an option so that prompts which have a 1-line and longer
version use the longer version by default.

namefit.diff shortens the names in wiz_create_item until they fit by trimming
the first few characters. As some names are now very long, this makes
recognition easier.

savesquelch.diff causes the game to remember squelch options from game to game
and causes the squelch options to be loaded and saved with other options, so
that the player need not squelch those things which are always useless on
starting a new game. Appropriate manipulation of preference files should allow
the player to achieve whatever effect is desired.
