OMG!!!!!!!!!   Let's be REALLY CAREFUL about getting back into the "wrap"
code...

Those of us who've used CM (and SC) for a LONG time have suffered through
line wrap bugs which I'm sure drove the developers nuts trying to solve.
The worst period was Feb/08-Nov/09 IIRC.  Line wrapping issues had been
bugging (sic) us since at least 2002 in sylpheed-claws.  The worst ones
would very randomly start wrapping
at
every
word;
and
it
took
nearly
two
years
to
find
the
trigger(s)...

[above was faked; sorry for freaking out the developers :) ]

IIRC, what Neels brings up is the very area of the code that caused all
that old pain...

Just for nostalgia, from my list archive, here's a prophetic message from
Colin in 2002(!!) on the subject of "re-wrapping short lines"... THANKS
again Colin, Paul, et al for your efforts at squashing all those bugs!
I'll back you if you don't want to touch that part of the [fragile]
code...  :)

Hello Darko,
I applied your patch (hoping it'll solve the disappearing line break) ;
but (as you can see upper, in your "To apply" explanation) I'm not really
sure that rewraping short lines should be automatic...
