Man tor - Old URL
In the man tor page, at the end completely, in the "BUGS" section, the URL "https://bugs.torproject.org/" should now be "https://gitlab.torproject.org/tpo".
"https://bugs.torproject.org/" automatically redirect you to "https://gitlab.torproject.org/tpo", so this is not a broken URL, but it could be nice to look up the entire Tor Project source code for this URL and replace it. This way, we could terminate the server that host "https://bugs.torproject.org/" and not leave old crumbs laying around. :)
