[Rd] how to document stuff most users don't want to see

[baptiste auguie]

If help was only displayed in the form of html pages, one could
perhaps mimic the javascript trick sometimes found in wikipedia, e.g.
"http://en.wikipedia.org/wiki/Mathematical_induction#Example" (see the
"show/hide" toggle at the bottom).

I don't see how this could work with plain text or pdf output.
