To obtain that effect, now @t{@slanted{...}} should be used (or, to be
sure that the context has no effect, @r{@t{@slanted{...}}}.

The precise formatting of @var in @code and similar commands, other than
being slanted was not (and is not) documented.

This is not directly related to the changes I proposed for @def*
commands lines.  Having @var always be roman with ligatures is Gavin
decision, although I don't disagree with that decision.  This is
somewhat related to the changes in @def* lines, as it seems better for
@var{} to be roman slanted without ligatures on @deftype* lines (rather
than slanted typewriter as it was before, and as it was documented).

I leave the decisions to Gavin, I would implement as consistently as
possible in LaTeX.
