In older Rubies, I believe that any string longer than one character,
as the argument to split, was interpreted as a regular expressions.
That changed at some point; strings are now always strings.

I thought the warning was supposed to disappear in the 1.8.0 final
release; either I'm wrong about that or it was just an oversight.
