Small optimization of LIKE patterns with > 1 trailing % 
Previously, LIKE pattern '%%%ab' became '.*.*ab'. Now, it becomes 'ab'
which is a bit faster (perhaps).

+ minor code cleanup + a minor doc update

Clarify that match() & like() assume UTF-8 
The previous explanation sentence

  "The regular expression works with the string as if it is a set of bytes."

suggested otherwise and since we don't have separate methods matchUTF8()
and likeUTF8(), it makes sense to clarify.
