TOC shows differently when using make incremental vs make html after make clean
The attached .rst files show the issue: make html with files as they are to get a base line. In index.rst, change the tocdepth to 1, then: incremental make html changes just the toc that appears on index.html make clean make html changes the toc in the index.html and also in the side-bar of heading1.html
I think incremental make should really do the same as clean make, although I really like the behaviour from the incremental change. So this is also a new-feature request.
