dired-aux.el better nroff suggestion

[jidanni]

! runs the command dired-do-shell-command
  which is an interactive compiled Lisp function in `dired-aux.el'.

which when placed on top of kernel-img.conf.5.gz
suggests     gunzip -qc * | tbl | nroff -man -h
when in fact gunzip -qc * | tbl | nroff -man -h | col -b
is needed, unless one likes ^H's, which are what one sees lots of
currently. Not sure the fate of non-ASCII though with col -b.

And it should be
gunzip -qc * |tbl|nroff -man -h|col -b
with less spaces as minibuffer space is at a premium.
