This whole change was not intended to work with the workflow of `C-h S'.
The problem is that `Info-build-toc' calls `Info-index-node' on the
temporary buffer where it fails to build the index.  Adding a line
`(Info-index-node "Top" file)' at the beginning of `Info-build-toc'
just before `with-temp-buffer' will fix this bug by building the
index outside of the temporary buffer, but I'd like to find
more elegant solution.
