Thanks.  However, since we are working with a git repository, the most
preferred solution is to check the repository out, apply the patches,
then simply say

  git diff > diff-file

Alternatively, people who work with the tarball should expand it
twice, namely into `groff.old' and `groff.new', for example, then
applying changes to `groff.new', then saying

  diff -ruN groff.old groff.new > diff-file
