As I said before, the main assumption in my suggestion is that there are things in trunk that "really should" be in some releasable version
Everything in trunk is now digested into three groups of commits, for inspection. These don't include whitespace changes, so the resulting files may be mis-indented and otherwise skewed, but we are looking for changes, not insignificant formatting;
Just the docs (sources, and generated)
Just win32 generated build gunk (presuming vcproj and CMake are both winners, there is a discussion to be had on .mak files before this gap is addressed)
Everything else (all the interesting stuff)
I expect committers will be mostly interested in the last link above.
