OK, it now does so in git, provided that the third argument to bcheck is not given. (This is an array of names of items that the caller is required to specify, known as "required-keys" in the bcheck documentation.) If required-keys is given and the user-bundle is null, bcheck returns non-zero indicating that the caller's input is insufficient.
