I'm playing with ReGIS graphics (in XTerm) and have noticed that things 
display differently depending on the line that the prompt is on.

It seems as if Zsh clears the remainder of the screen after the end of 
the prompt line.

If I clear the screen (^L) and then display the ReGIS graphic, the 
graphic flashes and then goes away.  I think this is because Zsh is 
redisplaying the prompt immediately after the cat command.  If I hit 
enter a number of times to cause the prompt to move further down the 
screen, such that it's in the graphic or below it, the part of the 
graphic that is above the prompt stays.

On a whim I tried Bash and it does not seem to suffer from this same 
clearing of the remainder of the screen issue.

Is this a Zsh setting?

I tried searching the zshall man page, and it seems as if all instances 
of "clear" either don't have to do with the screen or clear the entire 

Does anyone have any idea if this is a Zsh thing?  Or possibly something 
spurious I have in my prompt?

Any help / pointers would be appreciated.
