The flag "no_walk" is present in struct rev_info since a long time, but
so far has been in use exclusively by "git show".
With this flag, you can see all your refs, ordered by date of the last
commit:
$ git log --abbrev-commit --pretty=oneline --decorate --all --no-walk
which is extremely helpful if you have to juggle with a lot topic
branches, and do not remember in which one you introduced that uber
debug option, or simply want to get an overview what is cooking.
(Note that the "git log" invocation above does not output the same as
$ git show --abbrev-commit --pretty=oneline --decorate --all --quiet
since "git show" keeps the alphabetic order that "--all" returns the
refs in, even if the option "--date-order" was passed.)
For good measure, this also adds the "--do-walk" option which overrides
"--no-walk".

Actually, I tested this a lot in recent times, especially since I
started to use topic branches a lot more, to keep Junio happy.
And then I had an idea: Much better to let "git log" do the work,
since it already sorts the commits it shows by date. There is a
flag in the revision machinery, named "no_walk" which would tell
it to not traverse all ancestors.
Since I can make this an alias, it does not matter very much that
the command line is so long. However, since you can use different
pretty formats, this might be much more useful than the
--sort-by-date option for "git branch".
