sorting words ?

Geoff nailed it, all right.


The "word" chunk has always been loosely implemented, in that it can hardly be considered a truly delimited chunk at all, like an item or a line is. Even though it seems to have been included in the "family" of chunks.


Human brains seemed to have been able to accommodate this, most historic threads dealing with the such issues as the fact that multiple spaces "delimiting" words are not individually counted, or that quotes around multiple, er, words are a single word. And that delimiters reserved for other ("larger") chunks often find themselves embedded in a string of words, without affecting that string at all.


That sort of thing.


My point is that the advice you have been given, that you have to choose your words carefully, using some explicit delimiter and run with it, cuts through all that loosey-goosey stuff. In only that way can you control the text you are dealing with.

You explained the issue far better than me :)

The proposed meaning is the most sensible 'consistent' interpretation I think as it preserves the list structure if not the original data entirely.
