Fix ascent and descent commands.

For seven years and two days, the algorithm for ascent and descent has had an off-by-one error, and started at the wrong level.
Also, the message for failed descent has apparently never been right.
I figured I'd follow Java's conventions (as I see them) and have a body for the loop, so instead of incrementing the counter within the loop condition, I refactored the loop and put in a break statement.  I prefer the shorter version, but POLA wins in a foreign code base.
