Patch for real column number of errors

	I have written a small patch in order to have the real column
number of the error displayed. I have not tested it, because I do
not have time to get the validator completely installed on my computer,
and I consider it is a trivial modification of the source code.

	This patch have been produced from the source code available at
http://validator.w3.org/validator.tar.gz (downloaded a few minutes ago).
Please see attached file.
