Remove some useless linux-specific code which tried to modify
the routing table by running "/bin/ip". Because this code has
no error checking and failed silently, no one noticed it.
Noticed it now because it didn't compile with gcc-2.95.
Don't install useless documentation.
Install useful notes on protocol insecurity instead.
Tweak the man page a little. Dunno if anyone is still using
Bezeq ADSL modems that need the --quirks option, but move
the information here just in case.
Clean up MESSAGE; don't shout at everybody about security holes
in a particular kind of modem that's almost 10 years old.
