Note that paths with / won't always work in cmd when using built-in commands. For executables and their command lines, sure, but for at least some built-in commands you must use \ for path arguments because the parser otherwise parses an option. Not sure about CR-only, but Notepad only recently-ish (a year ago, perhaps) gained the ability to work with LF-only text files. Mind you, that's probably not a fix in Notepad, but really in the decades-old Win32 edit control ... (which might give a hint as to why this was neither much of a priority, nor probably an easy fix while not breaking anything else).
