[Evolution] Message display width too large

[Paul Smith <paul mad-scientist net>]

One thing that is annoying me supremely with Evo these days is how wide
the display of HTML messages is.  It's very often wider than the preview
window I use (which is plenty wide enough... probably about 45% of my
wide-screen display) which means text is filled to that width and I'm
constantly scrolling left and right to try to read messages.  It's quite
infuriating.

I've tried to get a handle on what is causing these extra-wide panels
and at least in some cases it appears to be long URLs in the signature.
 As part of my work I'm subscribed to many Google groups and they all
have a standard signature added to the bottom something like:

> -- 
> You received this message because you are subscribed to the Google Groups "Foo" group.
> > To unsubscribe from this group and stop receiving emails from it, send an email to foo+unsubscribe gmail 
> > com.
> > To post to this group, send email to foo gmail com.
> To view this discussion on the web visit
> https://groups.google.com/a/gmail.com/d/msgid/foo/verylongbase64encodedurlprefix%40mail.gmail.com.

In my experimentation it appears that the entire message is sized such
that that final URL can appear in the window without breaking it, and
tall other divisions and spans are also sized to match that.  I have to
admit that not all messages that come through the list have this issue
but many do.

This is really not good.  Even if there are some spans/divs which are
too wide for the pane the others should all be sized to appear within
the pane without scrolling.  E.g., it should be possible to have: 

 |-----panel width----------|
  some text some text some
  text some text some text

  verylongunsplittablelinewhichforcesthewidthtobelong
 |-----panel width----------|

Rather than what we get now where the entire message is filled to the
longest unsplittable line:

 |-----panel width----------|
  some text some text some text some text some text

  verylongunsplittablelinewhichforcesthewidthtobelong
 |-----panel width----------|

I don't know if there's anything Evo can do about this or whether it
just hands the entire content of the email over to Webkit and it's
Webkit that makes these decisions, but this issue really impacts the
usability of Evo (for me anyway).
