In my case, a misbehaving copy of SVN caused the test for this to have a '\r\n' line ending on Windows.  I fixed my SVN, but also realized that tolerance for whitespace might be valuable, particularly since a human might decide to change this without the gcc-config tool and neglect a trailing space.  It scared me that this was a condition where it would APPEAR to work well (ie, configure it to the 'latest', but not realize it is being ignored), then be surprised later.
