1. It has to be terminal independent; you can't just parse+construct escape
sequences. Use terminfo to get the information for the known attributes.
2. It can include printable characters; look at how the tcsh code does it.
For example, I can have an escape sequence in the prompt that sets the
xterm title bar.
