Pulled, but I wanted to talk about your merge "summary".

Your merge summaries seem to be entirely automatically generated,
which makes them less than great. I can see all that stuff in the git
tree already, just formatting it differently isn't all that useful.

For something like this late-rc pull when there are only a couple of
commits, the end result actually ends up looking almost like a summary
and all I did was remove the names that don't add to the description
(and are in the git commits).

For some of the bigger pull requests, the summary is almost anything
but, and the only real value-add is the grouping by subject area.

I really prefer a _summary_. Something that is human-legible. So that
when people read the merge commit log, they get an overview of what
changed, not a list of the details.

Again, when there are four commits, a "list of the details" pretty
much works. So the reason I react to _this_ pull request is mainly
that I have way more time to react to it during the late rc series
than I do earlier in the cycle..

OK. The starting point is obviously an automatically generated list of
commits, but I have been editing that a fair bit to drop boring commits
and combine multiple commits into a single line, and then sort it by
topic area etc.

But obviously I'm not editing it enough, so I'll try to summarise it
much more heavily.

I actually do like to include the names, just to give people a bit of
acknowledgment in the pull request, but I can drop them if you prefer.
Or maybe I'll just include a credits section at the bottom of the tag
with everyone's name once, and you can drop that from the commit?

Right.
