Here's that reroll. I now reset the entire struct in the error path of
`clear_...()`. Thus, the user that is reading `repo_fmt.hash_algo`
despite not being supposed to, can keep reading it, now knowing that the
value has a default value.

I also expanded on the documentation a little to point out that we'll
reset to the default struct state if we don't find any
"core.repositoryformatversion".
