Hi Ian,

Did it really work in v2.0.2, I wonder?

I cannot reproduce this issue with 2.0.2.  I suspect that this code has
been this way since early 1.9 releases, and is a consquence of switching
to the new syntax expander.

That said, this change was not mentioned in NEWS, and the documentation
has not been updated, so perhaps we should do something.  I would prefer
just to leave it as it is, unless you think that adding a compatibility
hack could help you somehow.  What do you think, Ian?

Andy
