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 (302953014e10dcef71b369e495dfb91b0fed705e)
\
N -- N -- N (69d7c9ef5642dee09b76da64d79f5f5e474501e5)
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.

commit 69d7c9ef5642dee09b76da64d79f5f5e474501e5
Author: Cyril Hrubis <metan(a)ucw.cz>

spiv: Fix image list counter
We have to add cur_file only and only if we are inside of a directory,
otherwise we end up with random position.

loaders: PNG: Wire up gamma tables.
Now the loader at least tries to set the gamma value for the pixmap,
which is later used by some of the resampling functions, etc.
