Thanks for the infos, Ralph!

Maybe Blake is right here, documents are mainly view on the monitor today and 
there the dashes do not look professional anymore.

It should not be a problem to change the \l,\L commands (or what is used in 
tbl) to \D'l ...'.  The \D request works correctly.

(Hopefully Blake doesn't test eqn, there are a lot more problems (in all 
ditroff variants) ...)
