via 948d5c23b0964eae013d0792109b79e41b410c2d (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 (aa97a856575a07325504a5905506b6b7bbc8ae90)
\
N -- N -- N (948d5c23b0964eae013d0792109b79e41b410c2d)
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.
