Similar to the previous patch, this is about better error messages
when .gitattributes happens to be a directory.
FWIW .gitignore code is also checked. There open() is used instead and
open("dir") does not fail on Linux. But the next read should fail with
EISDIR, which is a pretty good clue already. No idea how open() on
Windows behaves.
