Well, on my RedHat 7.3 system man produces the following command:

$ MANWIDTH=130 man -cd man 2>&1 | tail -1
  (cd /usr/share/man && (echo ".ll 11.7i"; echo ".pl 11i"; /usr/bin/gunzip -c '/usr/share/man/man1/man.1.gz') | /usr/bin/gtbl | /usr/bin/nroff -mandoc | /usr/bin/less -isr)

which is, AFAICS, the same as the one produced on Cygwin (except for
irrelevant details).  On RedHat 7.3, groff (well, nroff) heeds the ".ll"
command, and on Cygwin/RedHat 9 it doesn't.  I'm only assuming it's
because Cygwin/RedHat 9 have version 1.18.1, and RedHat 7.3 has 1.17.2.
