and reformat doc a bit. Based on Olaf Kirch's patch for openSUSE. Signed-off-by: Petr Vorel <pvorel@xxxxxxx> --- Hi Steve, original patch: https://build.opensuse.org/package/view_file/openSUSE:Factory/rpcbind/0031-rpcbind-manpage.patch?expand=1 Olaf removed note about multi-homed host and about adding 127.0.0.1 an ::1. I kept them, but maybe multi-homed is not relevant any more or not limited only to UDP. Feel free to modify the text to better accommodate to current usage.
