zsh propmts

	I'd like to thank everyone who had anything to do with the "%_" 
value for PS2 in zsh-3.0.0, I'm in love with it.

	I've been attempting to set up a prompt that will show me any 
non-zero return values, and print the names of any signal the last job 
recieved.  Right now I'm using two features of the shell to accomplish this:

function precmd { PSVAR=$signals[$?^128+1] }
PROMPT='%(?..%1(?.{%?}.%B{%?%2(v.. %v)}%b) )%m:%~%# '

	Unfortunately I end up with $PSVAR = '.' if no signal has occured 
because an invalid array subscription produces '.', such that my prompt 
looks like:

aic1:~% return 15
{15 .} aic1:~% ls -l            # I hit ^C here
{130 INT} darkstar:~%

	The trick here is that I can't execute anything in precmd that would 
effect $? or the "%?" value in the prompt is inaccurate.  How could I clean 
this so that PSVAR is set to a null string when $signals is given an invalid
