This is a small patch for Angband 2.9.2 to enable ego items to have maximum
to-hit, damage, AC and pval bonuses outside the range 0-255 without regard
to the item's cursed/uncursed status.

To use this patch, the ego items which should have a negative value for some
or all of these figures should have a negative value in e_info.txt rather a
LIGHT_CURSE flag and a positive value.
