Re: [Groff] Infinite loop in ms

Almost two years ago, Robert Goulding reported this:

I *think* that the patch below fixes it.  My simple tests worked well,
but I don't have larger documents with many footnotes; additionally,
my knowledge of ms is still very small.

Please test and report whether PS (and ASCII) output gives good
results -- they might be slightly different but should be still OK.
