Code review comment for lp:~gz/bzr-windows-installers/runtime_libraries_in_lib_881203

It doesn't require the installer built, but does need some rather specific testing which is hard to get someone else to do correctly. Basically, either a virgin windows copy without the runtimes is needed, or fiddling with internal SxS directories to emulate that state. Then it's possible to examine what handles the bzr process has open and confirm it's finding the libraries we ship so won't fail if they are not already installed. Hopefully I'll be able to do that testing later this week, when I fix my windows box.
