Wrong Path Separator from Some Archives.

[TurtleWilly]

Inspecting various archives I get mixed up path separators. For some archives it uses the expected slash ("/"), but for some other archives I get a backslash ("\"). Shouldn't this be transparently handled?

E.g. I download this archive: http://files.exotica.org.uk/?file=exotica/media%2Faudio%2FUnExoticA%2FGame%2FSeifert_Hannes%2F1869.lha (from: https://www.exotica.org.uk/wiki/1869)

    lha = lhafile.Lhafile("1869.lha")
    files = [info.filename for info in lha.infolist()]

    for filename in files:
        print(filename)

Result:

Not what I expected to see (I'm on macOS and/or Linux). I assume the archive was generated with Windows? Or something else goes wrong here. Other archives (e.g. downloaded from Aminet) behave correctly (I assume those were created on a Unixoid or on Amiga retro machines)

Any idea?
