Thanks, Dan, for your prototype. I have now prepared a patch that includes
your code into the lilypond distribution, and additionally uses it in the TOC
markup (*), so all toc entries automatically link to the corresponding pages.
Here's the patch:

Please review!
Thanks,
Reinhold
(*) Actually, the link to the corresponding label is currently hardcoded,
because I could not find a way to add the \with-link in the tocItemMarkup. The
main problem seems to be that the label needs to be a symbol, so I can't
retrieve it from the props via \fromproperty (which returns a markup). I have
tried (after adding toc:label to the props in table-of-contents)
tocItemMarkup = \markup \with-link \fromproperty #'toc:label \fill-line {
\fromproperty #'toc:text \fromproperty #'toc:page
}
as well as
tocItemMarkup = \markup \with-link #'toc:label \fill-line {
\fromproperty #'toc:text \fromproperty #'toc:page
}
Both of which don't work: The first because \fromproperty is a markup
function, while \with-link requires the label symbol; and the second because
toc:label is not directly defined as a variable, but rather has to be chain-
assoc-get'ed from the props... Any idea how to solve this and avoid hard-
coding the link?
