This patch is clearly not limited to the protection of data, as it
quotes variables that could in no way contain a space or have anything
to do with file paths.  As mentioned multiple times, using filenames
ore directories with spaces is asking for trouble, and I have no
interest in trying to support such a case.  I'm willing to consider a
*limited* patch that makes sure that cygport doesn't do something it
shouldn't in that case, but that's about it.
