I have several machines (which I don't admin :) where the development directory is a child of a "contains space" path (ugh, I know...). I figured, at least the "bootstrap" phase should handle this case :)
I tracked down all uses of full paths in bootstrap (I think), and updates all references/tests to correctly quote them. I tested in various "challenging" directories, and the patch I have appears to fix bootstrap to work as expected.
I'll submit a pull request.
Thanks,
Scott
