func WrapString

func WrapString(s string, lim uint) string

WrapString wraps the given string within lim width in characters.

Wrapping is currently naive and only happens at white-space. A future version of the library will implement smarter wrapping. This means that pathological cases can dramatically reach past the limit, such as a very long word. This is taken from: https://github.com/mitchellh/go-wordwrap/tree/f253961a26562056904822f2a52d4692347db1bd
