Lots of committers use the github editor (including myself).
The edit generates a commit for each file.

So, most of the pull-requests have multiple commits to fix a single issue.
To test these fixes, you now have to add multiple commit-id's to system_patches in order to see it in action.

Would it be a good idea to also allow a PR-url to be added as a patch ?
The github API makes it fairly easy to get all the commit-id's for a single pull-request.

demo code:

<?php
function get_content_from_github($url) {
    $ch = curl_init();
    curl_setopt($ch,CURLOPT_URL,$url);
    curl_setopt($ch,CURLOPT_RETURNTRANSFER,1); 
    curl_setopt($ch,CURLOPT_CONNECTTIMEOUT,1);
    //To comply with https://developer.github.com/v3/#user-agent-required
    curl_setopt($ch, CURLOPT_USERAGENT, "nothing"); 
    $content = curl_exec($ch);
    curl_close($ch);
    return $content;
}

function get_PR_commit_ids_from_github($url)
{
    $response=get_content_from_github($url);
    $json=json_decode($response, true);
    //var_dump($json);
    if(!empty($json)) {
        foreach($json as $item) {
            if(preg_match("/^[0-9a-f]{5,40}$/", $item['sha'])) {
                $result[] = $item['sha'];
            }
            else {
                $result = "";
            }
        }
    }
    else {
        $result = "" ;
    }

    return $result ; 
}

print_r(get_PR_commit_ids_from_github('https://api.github.com/repos/pfsense/pfsense/pulls/2318/commits'));
