gbranden pushed a commit to branch master
in repository groff.

commit 453a8aa7c8f8dd0c78160466301f81be8c40df2e
Author: G. Branden Robinson <address@hidden>
Date:   Mon May 1 12:17:51 2017 -0400

    Update grog(1) description.
    
    * Fix a sentence fragment when describing the groff options that grog
      deduces;
    * Undocument groff's -J flag, which is not documented in groff's own
      man page and cannot be expected to work because gideal does not exist
      yet.
    * Remove a discussion of the shell version of grog(1), which is not in
      the source tree and seems to have been dead for a while.

                grog: remove shell version. Add file perl_test.pl for
                      testing the available Perl version.
