Description:
        I'm not able to specify an interpreter in a shebang line if the path
        to this interpreter contains spaces. I'm not quite sure if this is
        considered a bug or if its just there for backwards compatibility but
        at least quoting etc. does not work for me.

        e.g.
        The directory "/home/fs/foo bar" contains the executable bin/python

        Now I have this python script
        -------------------
        #!/home/fs/foo bar/bin/python
        print 'foo bar'
        -------------------

        The shebang above obviously can't work because bash tries to find the
        executable named 'foo' and pass 'bar/bin/python' as a parameter.
        Therefore I tried to escape the path like in other bash scripts
        ('#!/home/fs/foo\ bar/bin/python') but this doesn't work either.
        Quotes (#!"/home/fs/foo bar/bin/python") don't cut it.

        IMHO bash should support every valid unix path for shebang lines.
