[it was eaten by majordomo, so here it is again]
I missed a feature a friend of mine put in getty back to the old 386BSD
days in getty so I have put in into our getty back.
It enables one to get a /etc/issue (for example) displayed by getty. One
may use a issue file per gettytab entry. The new keyword is "if".

:if=/etc/issue.terminal:\

:lm=\r\n%h login\72 :

:im=\r\n\r\n*** Keltia\r\n Welcomes Thee!\r\n\
\r\nFreeBSD unix, dialup access\r\n:lm=\r\n%h login\72 :
------------------------------------------------------------
The default is /etc/issue.
Please someone have a look at this and hopefully commit it ? Thanks.
