texinfo-6.7.92 pretest

[Gavin Smith]

The next pretest for the next Texinfo release has been uploaded to

https://alpha.gnu.org/gnu/texinfo/texinfo-6.7.92.tar.xz

We hope to release this in a few days' time barring the discovery of
any major issues.

There are minimal changes since the last pretest; we have made it to
make a pretest available with updated translations.  In addition, some
unused files in the JavaScript subdirectory have been removed.

The most significant changes since the last release (September 2019)
are to the HTML output of the texi2any conversion program. Support for
MathJax is added for formatting mathematical expressions. A
JavaScript-enhanced browsing interface is provided on an experimental
basis. The default output for HTML uses section names in preference to
node names, and simple lists of sub-sections replace Info-style menus.
There should be a significant speed-up due to more of the program
being written in C rather than Perl.

Pretest releases are made to give a chance for a new release to be
more widely tested, including on a variety of platforms.

Please send any comments to <bug-texinfo@gnu.org>.
