Thank you much Jiri!

Wlodek:  the tarball didn't include the generated docs. Add 
--enable-generate-docs to your the automated release builder. (Maybe 
need to add to DISTCHECK_CONFIGURE_FLAGS.)

I also did some trivial updates to master you may want to consider.
I am also going to remove the "beta1" reference from docs and the BIND10 
note from "make install" output. You may want to consider these also.
