When I run I get just the stupid blurb from FSF about breaking the standard
Unix documentation:

stitny~$ man mail
MAIL(1)                          User Commands                         MAIL(1)

NAME
       mail - manual page for mail (GNU Mailutils)

SYNOPSIS
       mail [OPTION...] [address...]

DESCRIPTION
       GNU mail -- the standard /bin/mail interface

REPORTING BUGS
       Report bugs to <bug-mailutils@gnu.org>.

SEE ALSO
       The full documentation for mail is maintained as a Texinfo manual.  If
       the info and mail programs are properly installed at your site, the
       command

              info mail

       should give you access to the complete manual.

FSF                                                                    MAIL(1)
stitny~$

However, here the situation is worse than usual. When running `info mail` there
isn���������t any, so I get this useless manpage again.

Yes, mailx(1) gives me the reasonable manpage, but there is now way how to get
there from mail(1).
