		BYKAuthorUnsubmitted Not Done Inline Actions It actually didn't break things that are not specifying an absolute path (see my tests below using just `php`) that said you have a valid point with `&&`. I just don't want to rely on `CMD.exe`'s horribly broken stuff but looks like the solution you want is to simply throw an exception when it sees a new line. Technically `LF` should work where as all `CR`s are removed automatically but I can't even get `LF` working for some reason.
