DESCRIPTION OF SUBMITTED PATCHES

All three patches are derived (But not directly) from Unangband
and apply to Angband 2.9.5-alpha.

------

295a-ego-high-brand.pat adds several new high ego branded weapons
to ego_items.txt.

The weapons are 'Foulheart', 'Thunderhead', 'Acid wit', 'Flametongue'
and 'Frostbite', and each has a brand and associated resist, one
stat bonus (Up to +3) and one random ability.

------

295a-fast-kill.pat modifies cmd1.c so that unused blows after a
monster has been slain do not count towards energy use for the turn.

This particular benefits warriors fighting breeders early on in the
game.

------

295a-pval-stack.pat adds pval and timeout stacking to Angband.

Pval stacks are applied to items that differ in pval,
particularly staffs and wands, but any item with similar pvals may
stack.

Timeout stacks (Including rods) allow items that are charging
and charged to stack, provided they are similar enough. This
includes stacking of any activatable item if similar enough.

Unlike many variants, this patch does not 'cheat' in the sense
that no information is lost when rods/staffs/wands etc. stack,
unless the new options stack_force_pvals or stack_force_timeouts
are selected, or an item is inscribed with '=s'.

Instead, the patch works quite hard to maintain information, 
by permitting stacking only under limited circumstances. Only
1 charging item may stack with charged items. Only items where
the pval differs by 1 may stack. However, this is 'good enough'
in the sense that depleting a known stack of wands or staffs
does not require unstacking at any point.

This patch is unnecessarily complicated by the fact that rods
use pval for storage of their timeout semantics rather than
timeout, and by the desire to support unidentified stacks.

It does munge cursed items slightly, but this was not considered
enough of a problem to worry about a clean solution, versus
the issue of allowing 'cursed' +0 pval objects.

The save.c/load.c modifications are #if'ed out for save file
compatibility. This causes pval stacks to 'round up' to the next
highest value, and timeout stacks to timeout all items in the stack
when saved and reloaded.

object description.

------

295a-pval-stacks.pat is the above patch, simplified to not handle
the unidentified cases.

This renders the patch, and resulting code a lot cleaner and
more comprehensible.
