[tex-live] pdfstartlink/pdfendlink and boxing level problems

[Karl Berry]

Hi Ulrike - for pdftex: your suggestions seem reasonable to me on the
face of it, and I don't see any immediate compatibility stoppers. But
implementing them is not something I am likely to ever get around to :(,
and I doubt Thanh has time these days. Maybe you or someone else would
be motivated to write the patches (+ docs + test cases)?

For LuaTeX: if no replies are forthcoming, you might write the
dev-luatex list. 

Thanks,
Karl
