agenda+ specdev character section

All,

It is already in the agenda for tomorrow, but I wanted to call it out 
anyway... so that you can read it in advance.

The current text is in this document:

  * https://w3c.github.io/bp-i18n-specdev/#characters
  * https://w3c.github.io/bp-i18n-specdev/#char_truncation

I substantially reworked both of these sections in the PR we reviewed 
last week. Since last week's call, I have gone even further, replacing 
most examples, and refrying most of the text.

Most notably, I merged the section derived from Character Model: 
Fundamentals text into the character introduction. I rewrote some of the 
requirements (very slightly) to be consistent with the text we just 
wrote. I disappeared items that were duplicative. I have stopped short 
of going into the other charmod-derived sections, but they also should 
be revisited (possibly with a heavy hand).

Please read the preview in advance of our discussion tomorrow. File 
comments, if you feel so moved, on the PR:

  * https://github.com/w3c/bp-i18n-specdev/pull/153
