tools: remove unused code in doc generation tool
Browse files Browse the repository at this point in the history
tools/doc/html.js includes code that looks for comments with
`start-include` and `end-include` for file inclusion. This seems to be
legacy code that is no longer used. The code only appears in the
table-of-contents generation function. The strings `start-include` and
`end-include` appear nowhere else in our tools and nowhere at all in our
docs.
