Due to inconsistent structure of spoiler logs, r- spells with "Equal
chance of any of the following" could end a line with a ':;". This just
find-and-replaces ':;' with ':' because that should never happen in
reality.
Rather than COMMANDS and its join to CHRACTERS['commands'] be a messy
cluster of \n, do some string parsing to make it look much cleaner and
more readable.
