Hi Gavin - somewhere in all the brace/indexing changes to texinfo.tex,
it seems that using @{ or @} inside @xref or other ref commands started
to fail (or maybe it never worked, I guess I'm not entirely sure, come
to think of it). Now, something like
@xref{a@}b}
gets (with texinfo.tex 2016-01-11.19):
./refbrace.tex:4: Missing @endcsname inserted.
<to be read again>
@indexrbrace
@}->{@indexrbrace
...
}
<argument> a@}
b
@xrefX ...@expandafter @Xthisreftitle @csname XR#1
Passing on since I saw it. I can't delve into it right now, but if you
don't have time I can get to it eventually. --thanks, k.
Trivial example file:
------
\input texinfo
@setfilename refbrace.info
@xref{a@}b}.
@xref{c@{d}.
@bye
