Redmine

I observed a problem with HTML links in the Ticket description input field (this applies also to wiki pages, of course). My text was this:

"69,95 €":http://www.reichelt.de/?ACTION=3;ARTICLE=87308;GROUPID=771;PROVID=2;&utm_source=Preisvergleich&utm_medium=CPC&utm_campaign=Preisvergleich_geizhals.at-de&psuma=geizhals.at-de&

Now look what Redmine does to it: 69,95 €%

As you can see, it shows an additional % symbol (which clearly doesn't exist) and it changes the last ampersand (&) to x%x in the URL.
I'm not sure, but this may be related to #10413.
