Ah-hah! That explains much. So a non-invasive fix would be to force
parseServiceFile to open the file in text mode; I think this would
work for that:

- f = fopen(serviceFile, "r");
+ f = fopen(serviceFile, "rt");

I don't think that that's really a good solution, because it does little
to prevent the same problem from reappearing elsewhere. But if we wanted
the smallest possible fix that might do.

I think we should have it go further and ignore any trailing isspace()
characters, so that trailing spaces don't cause problems either.
But in any case, the real stumbling block here is to get a project-wide
convention as to how to do it.
