Similar to TeX I think it is next to impossible to find a suitable
macro interface for the things you want to do.
Pity. Seems like an elegant concept, and very familiar.
a) Inter-word spaces: if larger than a threshold, expand the
inter-character space until these are reduced below it.
Instead of handling this with a macro I could imagine to set and unset
a flag which makes troff do that.
b) Is there an end-of-line character (like the soft hyphen above,
which might not have been explicit in the source) which we would
like to hang over the end of the line? Then slightly increase
the linelength of this line (or redefine "-" to have smaller
width, or whatever) so that it sticks out by the right amount.
Ditto.
Wasn't there a compile-time option for hanging punctuation at one
time, similar to the widow/orphan option? A quick grep doesn't turn
it up in the source, so perhaps I was hallucinating.
