two (2) questions about footnotes

["Thomas A. Schmitz" <thomas.schmitz@uni-bonn.de>]

Hi all,

I have two questions/problems about footnotes. Here is a minimal 
example, which does not compile in this form:

\unexpanded\def\MyRule{\blackrule[width=\textwidth,height=3pt]}
\setupfootnotes[rule=\MyRule]

\starttext
Test1: \index{Adam}Adam.\footnote{Test2: \index{Eve}Eve.}
\page
\placeregister [index]
\stoptext

(1) In my current project, the publisher wants the rule separating text 
and notes to extend across the entire text width. I found the \blackrule 
command and its use in the setup on the mailing list, many years ago, 
proposed by Steffen Wolfrum, but it doesn't work (anymore?); I get "tex 
error on line 3 in file /tmp/test.tex: ! Missing \endcsname inserted." 
Any hints?

(2) Again, something that has been asked on the mailing list, but not 
received any replies: would it be possible to have the index report that 
"Eve" occurs inside a footnote? So it says "Eve 1 n. 1" or something 
like that?

Thanks a lot, and all best

Thomas
