Early Roguelike Collection: arogue7/weapons.c annotate

annotate arogue7/weapons.c @ 168:82b2a046d151

arogue7: fix inventory display bug again. Removing the call to msg() in restore() resulted in msgw remaining as it was when the game was saved. This results in another display glitch like that fixed by r163. Adding an empty message puts msgw into a reliable state.
