st: sts graph: customizing -legend- option of -sts graph-

[Michael McCulloch <mm@pinest.org>]

Hello,
I've created a KM plot comparing two troups, and have used the 
-legend- option. Note in the 1st graph example that they're labeled 
1, 2, and 3.

Also note that in the second example, after dropping "drug 2", that 
even though 1 and 3 are left, they're labelled 1 and 2. If I've 
dropped 2, I'd like to see the labels say 1 and 3! Is there a way to 
do this?
