[texhax] fatal errors with footnote italics for critical edition

[Uwe Lück]

Sorry, mistyped, must be:

1. Put all footnote commands into the second argument of \edt=\edtext

2. In your document preamble, place

     \renewcommand{\morenoexpands}{\let\textit=0}

This extends \no at expands. If you get problems with \uline as well:

     \renewcommand{\morenoexpands}{\let\textit=0\let\uline=0}

and so on when new problems appear. Or \let\I=0 if you really never use 
\textit.

HTH -- Uwe.
