Hi all!

Recently I've made a patch for sh(1) manual page, that addresses this Problem
Report: https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=206284, that has
been around for quite a long time.

I've received some review-comments, that I did take into account.  I would
like to kindly ask hackers to take a look at it, because I think it would
be nice to have these changes in the tree.

It's my first more-or-less big patch and I'm ready to update it and
make some changes to it, if needed.

Differential Revision: https://reviews.freebsd.org/D49895

Thank you,
Artem.
