Make autolink references work with at least 2 symbols instead of 3

In our project, we use which by default as prefix uses just “ch” and now it’s impossible for us to adequately post the ticket number to work with autolink reference


Please support even 1 character, since many trackers allow X-123, e.g. Jetbrains YouTrack

in my project the prefix is “W-”, so making it 2 symbols instead of 3 would be great for us!
