The beeping in console (when holding down BACKSPACE to erase, or when
pressing TAB when there are more then one matching file, and when
working in vim) irritate quite meany users that learn to work in console.

The "smart" users can always turn that beeping ON if they want

The "less smart" users do not know how to turn it OFF and they are
annoyed by that.

Therefore I think the default should be OFF not ON for the beeping
(despite opinions like "they should look it up in docs" or "they should
type better" - this is not userfriendly)


appending
  set bell-style none
to
  /etc/inputrc

should fix it
