I am not sure why -- it may be [[my fault|todo/fix_javascript_load_ordering]] -- but it seems like plugins loads there Javascript resources *after* the `<body>` and `<html>` tags are closed. Here's an example from [my sandbox](https://anarc.at/sandbox/):

    <script src="../ikiwiki/ikiwiki.js" type="text/javascript" charset="utf-8"></script>
    <script src="../ikiwiki/relativedate.js" type="text/javascript" charset="utf-8"></script>  </body>
    </html>
    <script src="/ikiwiki/ikiwiki.js" type="text/javascript" charset="utf-8"></script>
    <script src="/ikiwiki/toggle.js" type="text/javascript" charset="utf-8"></script>

Here, `toggle.js` appaars after the `<html>` tag! Interestingly, this is not specific to that one plugin: the same thing happens, in reverse, in my [recent changes page](https://anarc.at/recentchanges/):

    <script src="../ikiwiki/ikiwiki.js" type="text/javascript" charset="utf-8"></script>
    <script src="../ikiwiki/toggle.js" type="text/javascript" charset="utf-8"></script>  </body>
    </html>
    <script src="/ikiwiki/ikiwiki.js" type="text/javascript" charset="utf-8"></script>
    <script src="/ikiwiki/relativedate.js" type="text/javascript" charset="utf-8"></script>

I am not sure what determines the order in the end.

I'm not sure what's going on, but it seems like the second time a `include_javascript`-like pattern is used, it fails to detect the `</body>` tag and appends the resources at the end instead. That could be because the `</body>` tag is not alone on its own line, which is actually fine in terms of comformity but confuses the regex...

I think the simplest solution is to add a newline when we add the javascript blob, to keep the assertion that body is on its own line. I have done so in the aforementioned patch, which is reproduced here for simplicty:

Sorry for the trouble, HTH! :)

PS: Note that it seems like browsers are happy to ignore the spec and load stuff outside of the `<html>` tag, thankfully. So this is mostly a cosmetic/conformity thing...
