It seems to work with ivy and ivy-avy, which introduce releases via
merge commits, as well as dash, which doesn't.  WDYT?

Is there a better/different way?  The only alternative I can think of is
to enter revisions manually in the :version-map, but that doesn't seem
desirable in the long run.

P.S. Sorry if this breaks anything on elpa.gnu.org :(.

Thanks,
