(function() {
    'use strict';
    function onurlchange() {
        if (window.location.pathname.startsWith('/shorts/')) {
            const href = window.location.href;
            const newHref = href.replace('/shorts/', '/watch?v=');
            console.log("Redirecting %s to %s", href, newHref);
            window.location.replace(newHref);
        }
    }
    if (window.onurlchange === null) { // if onurlchange supported
        window.addEventListener('urlchange', onurlchange);
    } else {
        window.setInterval(onurlchange, 500);
    }
    onurlchange();
})();

Maybe also try to update links before clicking them with something like.

    setInterval(function(){
        let links = document.getElementsByTagName('a');
        for (let link of links) {
            if(link.href.match("https://www.youtube.com/shorts/")) link.href = link.href.replace('/shorts/', '/watch?v=');
        }
    }, 500);

I thought about something like (though using MutationObserver instead), but I wanted to keep this userscript as lightweight as possible.
If you want a solution that also converts short links to watch links, try out https://github.com/YukisCoffee/yt-anti-shorts

Neat, thanks for the tip.

If using the Enhancer for YouTube extension, this is userscript is no longer useful with that extension's new "Convert Shorts" option

0.2: Updated to work on m.youtube.com as well
0.2.2: Add update URL and rename to "Redirect shorts" - this may require a uninstall+reinstall
