The erlang magics were in the old System V format; the "STANDARDS CONFORMANCE" section of the file(1) manpage explains the problem. The spaces just needed to be escaped with backslashes.
The upshot of this is that any file which happens to have "Tue" starting from the fourth byte would match; the PostScript file in question just happened to serendipitously hit it. A diff is attached against current git; the PostScript file in question is now identified properly with it applied. Adam Buchbinder
