Issue with poem length in 2nd_chamber

[brianjmalone]

Hey.

I had to modify ./chest to ever not get 'Wrong!' because of a trailing space in bash dungeon.

% Old code:
lock_val=$(cat poem | wc -l)
% Modified code:
lock_val=$(cat poem | wc -l | tr -d ' ')

Cheers.

Thank you for this, @brianjmalone. Your solution worked for me, and I learned about the translate characters tr command!
