Linebreak indication in pager - how to get rid of?

[Ulrich Scholz <Ulrich.Scholz@xxxxxxxxxxxxxxxxxxxx>]

Hi everybody,

the mutt pager prints a "+" as first character in a line if it breaks a line
that is too long.

That's fine - except if you want to copy and paste text from the console.
Then the "+" is copied, too, and alters your text.

How to get rid of the +?  Maybe one could toggle between displaying it and
not.

Thanks, Ulrich
