[vile] update on vi-book draft

[Thomas Dickey]

I've gone once-through the chapter 12, have to rework some of the
xvile treatment (partly to make room for comparable discussion
of winvile), and see that I ought-to-update the list of options
in appendix-c.  So it's progressing.  Additional eyes on the
text are welcome...
