Agreed. I just did my first commit with the shortened URL, and I didn't 
like it. If we want to use URLs, let's use the canonical 
https://www.postgresql.org/message-id/<message-id> format.

Right, we can't control the length of the URL, because it contains the 
message-id, which can be arbitrarily long.
