Author: Timothy B. Terriberry <tterribe@xiph.org>
Date:   Wed Jun 26 12:23:53 2013 +0200

    Fix version.mk parsing in genversion.bat.

    This was broken by the changes in 0482c82f to make it work with spaces.

    CMD interprets the quotes to mean the argument to FOR is a string,
    not a file name. Instead, we expand the path to a short file name.
