Petition confirmation email places space at end of confirmation URL
The space placed at the end of the URL in petition confirmation emails, which gets copied by some users, results in visiting an invalid URL.
I tried this with Icedove/Thunderbird and Abrowser/Firefox, Chromium and Midori (WebKit) but was not able to reproduce the issue. The person who reported this to us was using Disroot mail and Firefox.
It would be great if the trailing space was removed so that less users run into this problem.
