[authors] WG Ch3 Working with Text

[Jean Hollis Weber]

I have some additional material to add to this chapter. I hope to get to it 
in the next few days. I'll use the latest version (reviewed by MK and 
edited by GS). I'll let the list know when I'm done. The material is to 
fill in a couple of gaps rather than to document 2.3-related changes.
