AdiIRC

A lot of times when using certain IRC in-channel search services, they return the URL adorned by some kind of parentheses as a decoration on both sides of the URL string. Most of the time, AdiIRC matches such trailing characters as a part of the URL and upon clicking it, tries to load a webpage with such symbol(s) included, which usually ends in 404 or 403 error.

I'm attaching a screenshot in which you can see such behavior. When surrounding an URL with [], the closing bracket gets treated as the part of URL in 2 of 3 cases. Also, sometimes people who care for punctuation post something like "Hey guys, check this link: http:\\blah.blah. It's my new website!". The dot at the end of the url is entended as a sentence separator, not part of the URL but gets included into it by the parser anyway. In my opinion, regex patterns such as "\.\s" or "\.$" should be excluded from the url string by default since there are much more cases of mistakenly treating sentence end dot as a part of an url than there are actual URLs which actually look like that.
