The article ID parser looks for a string at the end of a URL path with
a bunch of hex digits. But it also has to handle user, tag, and search
URLs.
* /@ba5eba11
* /tag/0ddba11
* /search?q=ba5eba11
Some URLs are encoded as params. The parser used to look at the result
of the path first, then the params. But paths that ended in
`global-identity-2` messed that up because `2` is a hex digit at the
end of the path. This changes the logic to parse params first and paths
second which gets around this.
