Thanks for the fix (and with a test, too). Some questions...

I've looked at the context around this change, and I'm still not seeing
the connection between is_binary and broken symbolic links. That's more
a statement about my ignorance than about your patch -- after all, you
did fix the bug! -- but if you could go into more detail about exactly
how this fixes the problem, that would be great. (Putting the
explanation in a comment in the code might be best, in fact.)
