[patch] texinfmt.el; new var `texinfo-pre-format-hook'

[Wedler, Christoph]

When people use M-x texinfo-format-buffer together with my package
X-Symbol (<http://x-symbol.sourceforge.net/>), X-Symbol doesn't have any
chance to do its encoding, i.e., converting characters to the
corresponding TeXinfo sequences (e.g., converting ä to @"a).

The following patch should fix this (it's vs 1.68, but should also work
vs the current head revision 1.70).


2003-05-19  Christoph Wedler  <address@hidden>

        * textmodes/texinfmt.el (texinfo-pre-format-hook): New variable.
        (texinfo-format-region): Use it.
        (texinfo-format-buffer-1): Ditto.
