Subject: [PATCH 1/3] fix gfm extended autolinking requiring multiple
 backpedals

Add a test and fix that trailing punctuation is omitted in link URLs for
markdown like this:

    (See https://www.example.com/fhqwhgads.)

The trailing period and closing parenthesis should not be part of the
link URL.
