bug#796: 23.0.60; UTF-8 display

[Dieter Faulbaum]

This is not really a bug report but a wish list:

The display of the file:
http://www.cl.cam.ac.uk/~mgk25/ucs/examples/UTF-8-demo.txt
isn't as good as it should be.
(I use the monospace-9 font in emacs under Gnome.)
1. it seems to me, that the linespacing isn't correct (one pixel to much?)
2. the matrix-braces aren't well aligned
3. the box around "typography in plain text files" isn't well aligned
4. the combined characters don't look nice
5. the box drawing alignment tests (at the end) aren't okay

If you need a screenshot of this as an example, I can send it. But maybe
a "self test" should be enough to see what I mean.

But many thanks to bring the development of the emacs so fast forward.
