Re: backslashes in macro arguments

[Karl Berry]

     Other characters that need to be quoted in macro arguments are
     curly braces and backslash.

I committed a new http://ftp.gnu.org/gnu/texinfo/texinfo.tex (and in
gnulib, etc., etc.) which purports to handle \\ \{ \} in arguments to
macro calls.

However, \, can't be handled by the method I used, so @comma{} has to be
used.

I confess I am not sure if this change makes things better or worse,
overall.  I'd appreciate anyone who uses Texinfo macros giving it a try.

Thanks,
Karl
