When user wrapped lines manually, why is textwrap.fill() called on the
lines again?  E.g. when user wrapped manually at 78 columns, this will
create long - short - long - short lines (in german, why call this
effect "Kammquoting" (comb quoting)) .

I suggest to avoid textwrap.fill() when text contains '\n'.
