Footnotes in LaTeX

[Rob Beezer]

A whole lot of improvements and maintenance the past few days, and I've started
to lose track of what is still local on a branch, what is merged, what needs
announcing, and where. Ask here about surprises.

For the cognesceti - footnotes in LaTeX are now much more like a human would
write them. This is due to improvements in the "footnotehyper" package, which
we had explicitly turned off.

So we have to fight less-hard to counteract the effect of tcolorbox on
footnotes. No fancy XSL and we can override tcolorbox's ideas about a separate
counter. Bonus: we get hyperlinks at the footnote mark.

The actual content of the footnote still waits until the tcolorbox is done,
which could be several pages ahead. :-(

The real winner could be Oscar's "classic" LaTeX project. Footnotes should look
better in source, and with no (or minimal) tcolorbox, they should behave well.
My assistant thinks they were badly messed-up for "classic" anyway, as a result
of inheritiong all the old machinations (mea culpa).

Interesting reading, and all the details - my assistant's report at:
