I was reading back through old messsages to the mailing list and came
across a comment about trip.rc having "~!" in four places where it
should have "!~".  Being a damned fool, I went and fixed it, which of
course made me very unhappy because it revealed a problem with '. -i'
not printing a prompt like it should.  AAARGH! (Why couldn't I leave
well enough alone?)

For example on my system feeding the following script to rc makes it
stop and wait for user commands but doesn't ever print the prompt!

------------------------------------------------------------------------------
#! /bin/rc
echo 'This is test of ". -i"'
echo 'First we set the prompt to something we''ll recognize'
prompt=(PROMPT1 PROMPT2)
echo 'we now try to go interactive'
. -i /dev/tty
echo 'end of interaction'
------------------------------------------------------------------------------

Anybody got a clue?
