[dmd-internals] DMD documentation sucks

[Walter Bright via dmd-internals]

Andrei has run the source code to dmd through Ddoc (!) and put the results here:

     http://dlang.org/dmd-prerelease/

This clearly shows that dmd documentation stinks. This isn't going to get fixed 
overnight, but as we work on stuff keep in mind improving the documentation of 
things that you touch. At a minimum, Params: and Returns: sections.
