Generic function to add word-wrap support for other existing functions.

Wraps on spaces and respects newlines. Intentionally ignores non-unix newlines, tabs and more advanced text formatting.

Note: If we want rich text - we better have a higher level API to handle that (color, bold, switching fonts... etc).

Implementation Detail (UTF8).

Take care with single byte offsets here, since this is UTF8 we can't be sure a single byte is a single character.

This is only done when we know for sure the character is ASCII (newline or a space).
