I was able to reproduce it too. Thanks! Here's a fix. diff --git a/contrib/mm/mse.tmac b/contrib/mm/mse.tmac index dedfb10bb..8184b1434 100644 --- a/contrib/mm/mse.tmac +++ b/contrib/mm/mse.tmac @@ -43,7 +43,7 @@ http://savannah.gnu.org/bugs/?group=groff. .po \n[@po]u .pl \n[@pl]u . -.nr pg*footer-size 4\" 1v+footer+even/odd footer+1v +.nr pg*footer-size 4v\" 1v+footer+even/odd footer+1v .\"------------------------------------------------ .\" Dokumentnamn .ds LetDNAMN The problem is that someone (presumably macro package author Jörgen Hägg) left the scaling unit off of the `pg*footer-size` register assignment, so the size used for the page footer was 4 basic units instead of 4 vees. The former value is too small by five orders of magnitude (a factor of twelve thousand). I hadn't really looked at mse.tmac before but I observe that it forces the page dimensions (and offset) to fit, I think, A4 paper in portrait format if they are not already set via the L, W, and O registers. I suspect that will need to change to work more smoothly with groff's papersize.tmac macro file. I may need to add a comment about this (in English :-/) to the groff_mmse(7) page. In the meantime a good way to render documents requiring mmse will be as follows. $ groff -dpaper=a4 -mm -mmse -P -p -P a4 lorem-svenska.mm If a different paper format is desired, setting the aforementioned command-line registers will be important, so add the following flags. -rLxx -rWyy -rOzz ...where xx is the paper length, yy the line length, and zz the page offset. Use of scaling units ('c' for centimeters will be common, I reckon) is recommended. I'm attaching my own reproducer for your convenience. Its mostly equivalent to yours. Regards, Branden
