A difference between DWB mm and groff mm has been around for as long as groff mm itself, but seems never to have been documented or commented upon, as far as I can tell.  In Git it is now documented.

.IP \[bu]
.IR mm 's
.B nP
macro indented the second line of a paragraph to align it with the start
of the text of the first
(after the paragraph number);
.IR "groff mm" 's
does not.

There is no output line count argument to the `ti` request, so I suppose this would be done with with a diversion and a diversion trap to set a temporary indent for the second output line.

This ticket is to gather views on whether this would be worth implementing.
