Accidentally ran across a very small bug with 'Capitalize Tags'. I am ripping Tori Amos's "From The Choirgirl Hotel". It has a song titled "i i e e e" (yes, really ) and applying 'Capitalize Tags' turns it into "I I E E e".
It seems like when the last word of a title consists of only 1 letter, then that one does not get capitalized.
