Sherlock: Routine at AA14

See whether the character byte is a lower-case letter, then see whether the character byte is past the lower-case letters, then read the lowercase Handling Flag.

Handle lowercase letters (dictionary word characters).

Used by the routine at Print_Character. Turns an upper-case letter into lower case, remembers that a character has been printed on this line, and starts a new line when the character is a carriage return.
Convert uppercase letters to lowercase if needed.
