"ninja install_docs" should not run the "docs" target, because with the usual workflow ninja docs ninja install_docs the documentation would be built twice. That of course means that "ninja install_docs" will fail if "ninja docs" wasn't run before. Analogous for html_docs, qch_docs, the repository-level and module-level documentation targets.
