[[MediaWiki:passwordreset-emailtext-ip]] and [[MediaWiki:passwordreset-emailtext-user]]
In the e-mail bodies of messages Passwordreset-emailtext-ip and Passwordreset-emailtext-user, there is parameter $4, which is the base URL of the wiki, in (round) brackets. This is unfortunate for many e-mail browsers that tend to make the closing bracket a part of the URL and present wrong links. By the way, standard in that situation are angle brackets. I suggest either to use them, or not to use any adjacent punctuation at all.
No problem changing it in all languages as far as I'm concerned.
