Missing documentation for `String::split`

[terhechte]

split has the following to say regarding the types that the parameter Pattern can have:

The pattern can be a &str, [char], or a closure that determines the split.

However, another, undocumented, option is that the pattern can also be [&str] and then each split uses the next item from the slice. This is an awesome feature that is kinda difficult to figure out.
