(I've sent this mail before, but I think the mailing list troubles might have
eaten it).

Hi Hans,

> i uploaded a beta zip with two extra hooks
I see the hooks, but I can't find the spot where they are called? It seems you
missed this part of my patch?

Also, I think you didn't update the definition of \type to use the typesingle
lua function I proposed, which means that \type{} commands won't get
begin_of_buffer and end_of_buffer called at all.

Am I missing something, or did you? Will you fix this, or should I prepare a
new patch?

This change looks good indeed, those long function names weren't all that
pretty.

> you need to adapt the wiki accordingly
I will, as soon as I get things working again :-)
