Older versions of fossil used to do something different that was less confusing.

In the case of an ambiguous hash prefix like this that matches multiple hashes in the fossil db, it would be most helpful if the result page simply showed a list of the possible hash matches and their types so that it's a simple matter to click on the one you want to go there.
