  Bugs Fixed

     * Documentation cleanups: full and correct return docs including an
       errnum where necessary; make sure we have a link to SUSv3 wherever
       available; add an ', if successful' suffix to a normap return
       result followed by error return results; fixed several typos.

     * Update fork2.lua example to match current APIs
