A question on the "Usually" part, mainly for clarification.  Fossil will
currently display only as many characters as needed for the hash so that
the hash is "unique" in the repository.  So, IF (yes, it is a big if :-) )
there is a SHA1 hash and a SHA3 hash where the first 40 characters match
then Fossil will display the first 41 characters of the SHA3 hash.  Is this
correct?

Also are there any thoughts on about a "rehash" command that would go
through the repository and change all the SHA1 hashes to SHA3?

Will there be any measurements taken to find out how much of an impact
there will be to the repository by changing to SHA3?  Things like
repository size, rebuild time, and other more interesting details.  I ask
only out of curiosity, not that I think it will be an issue.
