I would concentrate on getting the unrelated bug fix sorted...

But, I would probably add something along the lines of:

#################################
#
# Something is wrong here
# We need to resolve this
# 
# Search for what it's doing,
# check it's doing it right,
# then correct the code or
# the comment
#
#################################

# Add one to $i
$i = $i - 1;

So, at the very least, it doesn't get lost in a mass of code again...
