System/library limitation/design?

Converts the specified string to title case (except for words that are entirely in uppercase, which are considered to be acronyms).

Maybe in the future it’ll be smarter, but for now it just uppercases the first letter in a group of letters, and tries to pay attention to non-letters and word breaks. It also tries to keep acronyms all upper-case.
