emacs: Fix email/news quoting.

The Message mode's default quoting is `> ' except for blank and quoted
lines, which get `>'.  This is right for blank lines (avoids trailing
spaces), but is wrong for quoted lines.  So, hacketty hack, we fix it to
use `> ' for everything and trim off trailing spaces manually.
