       via  5fc96ed11f3b6312f09ecb34417eb9eac6e69a32 (commit)

This update added new revisions after undoing existing revisions.  That is
to say, the old revision is not a strict subset of the new revision.  This
situation occurs when you --force push a change and generate a repository
containing something like this:

 * -- * -- B -- O -- O -- O (858af9a6b965b39d5abb7f779b9d082528c88a2b)
            \
             N -- N -- N (5fc96ed11f3b6312f09ecb34417eb9eac6e69a32)

When this happens we assume that you've already had alert emails for all
of the O revisions, and so we here report only the revisions in the N
branch from the common base, B.

Those revisions listed above that are new to this repository have
not appeared on any other notification email; so we list those
revisions in full, below.
