HTML4.0 hrefs

It would be easier to use a local copy of this document if all hrefs 
referred to URLs with "htm" suffixes rather than "html". Netscape
Communicator under Windows '95 gets all confused.  So does Microsoft
Explorer 4.0.

I've hacked a substitution, also shortening filenames internally
to 8.3 DOS-style filenames.

Result seems to work fine for local references.
