    Fix white space handling in file names

    Previously, when using data_files with a glob that matched a file with
    whitespace in the name, pip would error with a message that the file
    does not exist, e.g:

        error: can't copy 'ansible/roles/yatesr.timezone/templates/timezone-Arch': doesn't exist or not a regular file

    The problem was that ansible/roles/yatesr.timezone/templates/timezone-Arch
    was a truncated form of the actual filename:

        ansible/roles/yatesr.timezone/templates/timezone-Arch Linux.j2

    Note the space in the filename and that it has been split on this space.

    This change allows you to use a glob that matches files with whitespace
    in the name. It does this by quoting the path.
