Right, I think your specific use-case is non-standard and doesn't
really match what the available documentation.

This makes sense - because you're not expecting to serve the
file via HTTP, but instead via a local file-system access.
Your solution is correct:
* Load via filesystem path, rather than by the URL, from beneath
/usr/share/javascript/.

In 99% of cases, where the library is intended to be included by a
file fetched via HTTP, the documentation is correct as-is.
Its only if you're trying to load jQuery via something that doesn't
use a web-server, and is instead found on the filesystem, that we
need to document the solution.

To handle that I'd almost suggest making a code-change. Linking
/usr/share/javascript/jquery/jquery.js to the directory of the
output - and then loading <script src="jquery.js"></script> - such
that if the directory is moved the source still works,.
