Great, let's settle with the in-commit tag "Dont-Auto-Build" for now :)

"git branch --edit-description" could potentially be the most elegant
solution, unfortunately for now there seems no way for me to retrieve
the branch description edited by you..

Another alternative, git tag, has the problem that it goes out of sync
every time you do rebase, which will sure happen a lot for early RFC
patches.
