Thanks for noticing.  That's because mercurial-common is
architecture:all[1].

How about something like this patch?  mercurial already depends on a
specific version of mercurial-common, so I wonder why
mercurial-common's dependency in the other direction needs to be
versioned at all.  For that matter, why does mercurial-common need any
dependency on mercurial?  (I would think the true story is something
like Enhances, which wouldn't need to be declared because of the
Depends in the other direction.)
