Ack. It would help if isWhitespace existed. I thought it did as a part of our isAlpha etc methods. I need to check my assumptions more.
I still think isWhitespace is a bit better as it matches the naming/functionality of Character.isWhitespace (as char's cannot be null) and the StringUtils general functionality of trying to do the obvious/quietest thing on null, but it's not that important.
