Thanks!  I knew I had seen a solution to this involving something 
like ps1 and ps2, but the things I kept finding referred to the 
bash/sh PS1 and PS2 prompt level variables.  All it took was 
learning that they *really were* ps1 and ps2...just namespaced 
off into the sys module.

Works like a charm.
