Re: texi2dvi failes to encode 'a' and 'e' with ogonek

[Karl Berry]

It'll take me another day or two to write all the documentation, but
here's a patch for texinfo.tex to support @ogonek{CHAR} and also the
literal [AE]ogonek in Latin 2 and UTF-8.  (You can also get it from CVS
or ftp://tug.org/tex/texinfo.tex if the patch doesn't apply.)

Please let me know if problems.

Thanks,
Karl
