Hacking the stylesheet is the wrong way to solve that problem.

The reason the SGML backend does that is that if it doesn't add
whitespace anywhere, the output would often have extremely long lines
(sometimes the entire output would be a single line), but it doesn't
know anything about the semantics of the output DTD, so it is only safe
to add linebreaks inside tags.

It would be easy to hack the SGML backend to add an option not to add
any whitespace, or to otherwise customize the whitespace handlings.

Alternatively just run the output through a HTML pretty printer (like
Dave Raggett's tidy).
