Comment 5 for bug 1647485

debdiffs added for t/x/y/z that add all 3 patches proposed in the upstream bug, that:
-change udev to replace spaces in all SYMLINK values by default (unless option string_escape=none is used by a rule)
-update test/udev-test.pl test case to use string_escape=none option for test cases that use spaces in their SYMLINK value, and expect the spaces to not be replaced
-update man page to clarify that spaces in SYMLINK values will be replaced with underscore, unless string_escape=none option is used
