    shar: add a deprecation notice
    
    The shar(1) program is simple, but the fundamental idea of a sh archive
    is risky at best and one that we probably shouldn't be promoting as
    prominently as a program in $PATH and a manpage.  Let's deprecate and
    remove it, since the same functionality can easily be found in
    tar(1) instead.
