important Texinfo changes

[Werner LEMBERG]

Folks,


the current git version of `texinfo.tex` (which will eventually become
part of the next Texinfo version) has some important changes that
heavily influence the layout of `@def*` commands.  Since groff needs a
lot of macro trickery to get good results I strongly suggest that you
test the changes and report any problems to 'bug-texinfo@gnu.org'.

  https://git.savannah.gnu.org/cgit/texinfo.git/tree/doc/texinfo.tex

I also suggest that you test with a git version of `makeinfo` because
`groff.texi` relies on its macro expansion (i.e., option
`--macro-expand`).

BTW, recent versions of `texi2dvi --help` no longer explain what
`--batch` or `-e` is good for: option `--batch` of `texi2dvi` is the
default since Texinfo 6.7 (2019) and thus deprecated, option `-e` (to
be replaced with `-E`) has been obsoleted in Texinfo 6.3 (2016).  The
good news is that the old options still work :-)
