Yes, but what about having various lines refering all to the same host?
There is no way to have it done fast, once, by deleting *all* refering
lines, since there is no way to find out what other lines match this
particular host. Such scenario is common in dhcp environments where you
are connecting to hosts changing their IP with the next boot.
