Re: backslash no longer works in indices

[Karl Berry]

    there has been an backwards incompatible
    change within texinfo.tex (to follow the documentation) 

I don't recall for sure, but I think it's far more likely that I wrote a
new item in the documentation to describe the behavior.  I can say for
sure that no one changed texinfo.tex to explicitly make this behavior
happen -- it is endemic to TeX macro processing and it never behaved any
other way since the @macro support in texinfo.tex was written.

If I could change it to make @funindex \q work, I would, but it's not
feasible.

    the CVS version of makeinfo 

As I've said before, the C implementation of makeinfo is dead and rotting.
Ignore its existence in CVS.

Patrice, can you check how TP behaves with @funindex \\q?

Werner/Phil, I'm afraid there is no good answer for your document with
the software as it stands now.  Sorry.
