Subject: [PATCH] Prevent adjusting items to the dash inventory letter

The #adjust command allowed, due to compactified buf, putting
items into the '-' inventory letter, which is usually reserved
for "empty hands", zeroobj. This caused problems down the line
when user was allowed to pick that letter for dropping.
