Problem Description

URLs in comment texts are often directly followed by a comma "," or a closing parenthesis ")". These should be removed when linkifying the URL, such that control-clicking them works.

What steps reproduce the problem?

Enter this code in Spyder:

# Our example is https://www.wikipedia.org,
# while we could have also used the Spyder homepage (https://www.spyder-ide.org).

Observe which part of the comment is underlined by the URL detection.
Try to open the pages by control-clicking.

What is the expected output? What do you see instead?

Both the comma and the closing bracket in the comment should not be underlined as well as the actual link, but they are.
1. The pages should open by control-clicking, but they don't, because the URLs are wrong.
