xref wrapped in macros

[Akim Demaille]

Hi!

I have some weird warnings demonstrating a bizarre behavior when a ref
is made from a macro:

src/texinfo/test-cases % eof xref-in-macro.texi                  nostromo 13:28
: -------------------- xref-in-macro.texi ----------------------
cat > xref-in-macro.texi << \EOF
\input texinfo   @c -*-texinfo-*-
@setfilename error
@settitle error

@macro exref{arg}
@xref{\arg\}
@end macro

@ifnottex
@node Top
@top TITLE
@end ifnottex

@exref{Top}.

@bye
EOF
: ------------------------------------------------------------
src/texinfo/test-cases % makeinfo xref-in-macro.texi             nostromo 13:29
xref-in-macro.texi:14: avertissement: End of file reached while looking for `.' 
or `,'.

This is CVS makeinfo.


Thanks!
