I'm not sure how combining SHA-1 and SHA-256 in a single git
repo will work, eventually. But this is an obvious place to do
the right thing if we ever see a 64-byte hex string (unless git
adds support for another hash which uses 64-byte hex string
representations, which would break many assumptions elsewhere,
too...).
