These two bugs have now been fixed. (There was a little fallout from bug 26755, but hopefully that has been taken care of, too.)

prepare-ChangeLog now puts the bug title and URL first, then the "Reviewed by" line. commit-log-editor no longer reorders the ChangeLog contents (other than extracting common lines to the top of the commit message). webkit-patch now uses commit-log-editor to create its commit messages.

I think this has made some of our tools a lot more useful. (See, e.g., <http://trac.webkit.org/log/trunk?rev=90579&stop_rev=90540>. The switch from the old commit messages to the new ones is quite obvious.) I think it's also a slight improvement in readability of ChangeLogs, as in many cases the bug title is a description of the change.

I'm going to drop the "put a one-line summary at the top of your commit message" suggestion for now. I think I've caused enough change for one email thread. :-)
