ElideMiddleInPlace()

void ElideMiddleInPlace	(	std::string &	str,
		size_t	max_width
	)

Elide the given string str with '...' in the middle if the length exceeds max_width.

Note that this handles ANSI color sequences properly (non-color related sequences are ignored, but using them would wreak the cursor position or terminal state anyway).
