ANSI bg colour outside of prompt area

[junkcommander0@gmail.com]

Hey Guys!

This is my first ever mailing list post, please let me know if I'm doing 
this improperly!!

I was wondering if anyone has had any success setting BG colours in 
their terminal with ANSI escape sequences or with some other method.  I 
had some aliases with escape sequences that I used for bash and shell 
that would change the background colour. The colour was never reset, and 
clearing the screen would change the entire terminal's background 
colour.

	ex: 
	echo -ne "\033[1;33;43m"


In zsh, the background color gets reset once the characters have been 
printed.
	ex:
	kecho -ne "\033[1;33;43m abcdefg"


I've tried using zle_highlight, or appending to the end of PROMPT, but 
(as documented) it only colours the editeable lines in the terminal:
	ex:
	zle_highlight=(default:bg=yellow);
	PROMPT="%K%{yellow%}$PROMPT"

I also came across a neat tweak on the mailing list that allows you to 
change the colour of errors (which is neat, but still not what I'm 
looking for):
	ex:
	preexec() { echo -en "preexec () { echo -n "\033[11;43m"; }


I'm running out of steam though I hoped maybe that precmd or something 
like that might yield some results but I'm a little stuck at the moment.  
Any chance that any of you might be able to nudge me in a different 
direction?

Thanks Again,
- Will
