Fix some inconsistencies in armor handling. The 'T' command
wouldn't let you take off a suit or shirt if you were wielding a
cursed two-handed weapon, which makes sense; however, the 'A'
command neglected to impose the same restriction. Also, the 'W'
command had some code intended to prevent you from donning a suit
or shirt while wielding such a cursed weapon, but it didn't work.
This patch fixes the 'A' command's checks for whether an
item can be removed and it makes the 'T' and 'R' commands use the
same code as 'A' instead of maintaining multiple sets of checks.
It also fixes the trivial 'W' problem and attempts to prevent the
sequence of 1) get interrupted while removing a set of equipment
including suit and/or shirt; 2) wield a cursed two-handed weapon
or have already wielded one become cursed; 3) resume removing
armor via 'A' but I haven't tried to trigger that situation to
confirm the bug or this fix.
Eliminate or at least reduce one of the idiosyncratic differences
between enchant weapon and enchant armor: make reading enchant weapon
discover that scroll if the effect is adequately discernible, instead
of always asking the player to supply a name for it. If your weapon
is identified and its +/- enchantment value goes up, or you're wielding
a worm tooth and it transforms into a crysknife, you learn the scroll.
However for the negative effect of a cursed one, that's only applicable
when the scroll is already known to be cursed.
