Feature summary: I want the link to a user's upload log at Special:ListFiles/USER to work however the URL is formatted.

Use case(s): If the URL is written as such: https://en.wikipedia.org/wiki/Special:ListFiles/Jonteemil the link works. If the URL is written as such: https://en.wikipedia.org/wiki/Special:ListFiles?user=Jonteemil the link doesn't work, it just takes you to the generic upload log instead. The reason for this is that #titleparts is used to get the username from the URL and it of course can't when there isn't any slash to seperate the username from the rest of the URL.

Benefits: The user=Jonteemil version of the URL is generated when the checkbox for showing previous versions is checked. If you uncheck it, the user=Jonteemil version is still generated. So if you have checked or checked and then unchecked the checkbox the link doesn't take you to the user's upload log. The same is true for when you change the number of files to show per page or if you change the page.
