The option requiring the explicit reference repositories is a bit of overkill:
the alternates in the original repository *are* reference repositories and
would be dissociated from should one pass any reference repository (even an
unrelated one).

IIUC, I should validate the alternates in the source repository...
But, the only thing the user looses if it is not validated, is the nice
warning regarding no reference repositories to dissociate from, right?
So maybe we can just remove the reset of option_dissociate and be done with
it? I would actually suggest removing the warning as well: the alternates are
something to dissociate from. And I see no harm otherwise.
How about this instead?
