o Bring the static ``ttystate'' into struct prompt so that the tilde context is per prompt and not global. o Comment the remaining static variables so that it's clear why they're static. o Add some XXX comments suggesting that our interface list and our hostname should be re-generated after a signal (say SIGUSR1) so that a machine with PCCARDs has a chance.
