Oops. I have been processing the patches in my "after 1.6.3" mailbox from the rc freeze period and have already queued this one, but the re-integration of four branches is taking a bit longer than usual. It takes too much time to run tests (and as a part of my build procedure I do docs, too) for all integration branches, and until they all pass tests on Debian5 (primary development box) and Fedora9 (at k.org) I do not push the result out, so it is a bit painful for me to replace a patch once a day's testing cycle begins. I was about ready to push the whole thing out, but with this much improved commit log message, it is _very tempting_ to rewind what I queued and redo today's cycle. I'll see how many other such (re)-sends I've got; most likely I'll redo today's cycle after replacing what I earlier have queued with this and your 'checkout' one, and also a patch from Dave Olszewski I want to replace with the 'real' one. Thanks.
