Previously there were no check at all on @w content.  I assumed that @w
could only contain "simple text" which meant all the inline @-commands
except for 'titlefont', 'anchor', 'footnote', 'verb', 'xref', 'ref',
'pxref', 'inforef'.

Actually, for this specific example it seems to me that the code put on
@w is too long to allow for correct display.  I checked in HTML, and
indeed, the non breakable part seems to me to be too long to allow for
good rendering, unless the browser width is within a specific range.
Wouldn't you obtain the effect you want or even something better by
simply using @w for the arguments of the @pxref instead, possible adding
a third argument in @w?

It could also be possible to accept more commands in @w without giving a
warning.
