Don't fold uppercase to lowercase makemap command-line switch

Normally, the key is converted to lowercase before being stored in the database. When the key entries are case-sensitive, the -f switch can be used to prevent conversion to lowercase. When tokens in rule sets are later looked up in the database, you can choose (with the K command, Section 23.2) to leave those tokens as is or convert them to lowercase before the comparison to keys. This switch and the K command should parallel each other.
