I was expecting to see an documentation update to for-each-ref (and
probably branch and tag) so that what this new atom means.  Is it
that %(is-base:<commit>) interpolates to <commit> for a ref that is an
ancestor of <commit>, and interpolates to an empty string for a ref
that is not, or something?

Thanks.
