This commit fixes the most common scan listings. Still trailing
whitespace will be generated by legacy scan listings.

The formatfield workaround in etc/mhl.headers is a bit clumsy.
Maybe, an mhl variable should be defined for this case ... or
better not, to keep the mh-format and the mhl functions orthogonal.
