This has been fixed.

Actually, the custom wrapper for CGI.pm was fine but it doesn't work around these bugs. The wrapper causes '[' and ']' to be escaped in the appropriate places of generated HTML and adds newlines after generated <tr> tags (and defines a couple of methods that are never actually used at this point).

There are a couple of (design) bugs in CGI.pm related to escaping the HTML of elements for which HTML does not need to be escaped. I have finally filed a bug related to those. You would think that fixing them would require making allowance for backward compatibility. But, maybe not...

I've once again commented out a few lines (using "#!#" so they are easy to find) of a copy of CGI.pm and fixed those design bugs. I've also fixed a few changes to CGI.pm that broke backward compatibility (hence my ending to the previous paragraph).
