[perl #118025] Case insensitive parsing causes -d to be incorrectly parsed

Thanks, applied as 811152076124f23ce4fce5eaf783077468102f6a.

Actually, I seem to have either duplicated your patch or applied it with amendments and without 
attribution.  In any case, I apologize that you did not get credit on the commit, which you 
(Andrew) caused to occur.

You'll just have to contribute more. ;)  Thanks, again!
