If i define...
fn prompt {echo -n $HOSTNAME^'$'}
prompt=''
...I get...
<machine>$
...for prompt.
The Problem:
Using readline to step back in history, the prompt disappears after
a few steps. Is this a bug in readline or rc? What can I do to avoid it?
I haven't found this in 'rc-list', so hopefully it hasn't been
discussed yet (orelse flame me). :-)

From my .rcrc, before I got sick of it and switched back to a bare semicolon:
#fn prompt { prompt=(`{whoami}^'@'`{hostname}^':'^`{pwd}^'; ' '' ); stty sane }
(It's "prompt", not "ps1"....)

readline is called as readline(prompt_string) so that moving backwards and
forwards in the history will end up redrawing the screen to look right.
In your case, readline is being called with a null prompt, so nothing is
printed.
(Forgive me, I don't know the rc syntax very well, but wouldn't this or
something like it work?
p1=`{echo -n $HOSTNAME^'$'}
p2=';'
prompt=( $p1^' ' $p2^' ' )
I'd better quit before I get confused...)
