Does it use the third argument if present?
Yes (test file below).
Ok, but then it seems to me that omitting the argument and have it
automatically set is even better.
I agree (though it would have been nice to hear from James if he'd
really want to use it).
Maybe there could be a command along
@setxrefautomaticsectiontitle
I don't think we need the "set" in the name, just
@xrefautomaticsectiontitle
?
If that suits you, I'll add it to texinfo.tex and the doc.
Thanks,
Karl
