[Development] FW: Backwards compatibiltiy break in Qt 5.5

[Knoll Lars]

Agree with Thiago. Backslash is a good escape character, as it’s used in
pretty much all programming languages for that. If you want unescaped
paths, you can use noquote, or print the paths using slashes (using
QDir::fromNativeSeparators()).

Cheers,
Lars
