bug#927: vc-bzr.el with cygwin bzr

A better solution would be to write a w32 wrapper for Bzr (an plain w32
executable that runs python with the bzr script), so that it does not
rely on cygwin's own handling of #!

After all, does Cygwin's bzr work with any other program that's not part
of Cygwin?  I'd guess not, which is why I think the problem is not
specific to Emacs.
