I wanted -ms like output. For example:

This is a paragraph.
-ms does this:
a+b=c            (1)
-mm does this
a+b=c              (1)

The left -mm bracket is aligned wrongly IMHO (I've never seen something similar 
in any article or book).

As for me submitting patches;

I'd love to. But do there exist any good groff macro writing tutorials. The 
only one I know of is UTP. Furthermore... -ms and -mm use groff-only features, 
so ... I'd prefer to submit my own "extension" macro, rather than change an 
existing one.

About the paragraph line style, it's effect looks like this:
--------------------
This is a paragraph.

(line above a paragraph)

This is a paragraph.
--------------------

(line below a paragraph). Similar to underline, just that it underlines a whole 
paragraph, not a given set of words.
