I have the following function (for bash1.08.1)

zless() {
for i in $* ; do
	zcat $i | less
done
}

What I'd like to be able to do is interrupt the function.  When I interrupt I
can only get (not surprisingly) the "zcat | less".  And the for loop continues
on it's merry way.  I thought putting a "trap 'return' 2" as the first line 
might work, but it didn't.  Any suggestions?

Thanks,
Eric.
