Re: `\\' doesn't work in @math

    look also at line 8732 of groff.texinfo: I can't use @{ as an argument

I suggest not using your complex macros for that case.  Sorry, but I
could spend days attempting to debug this one case.  Yes, I know, macros suck.

This minimal non-macro test worked for me with both texi2dvi -e and
texinfo.tex, which I think is the equivalent of what your macros end up doing:

\input texinfo
@setfilename macbrace.info

@deffn Escape @address@hidden
Using @{ with @@deffn.
@end deffn

@bye


HTH,
