I wasn't going to worry about an untracked .gitattributes. The reasons
for disallowing symlinked .gitattributes are:

  - it doesn't behave the same when accessed internally via the tree
    objects

  - malicious symlinks that try to leave the repository

Neither of those issues is at play if your symlink .gitattributes file
isn't tracked. So there's some inconsistency in the sense that it
"works" until you try to "git add" it. But either you aren't going to
add it (in which case it's a feature that it works), or you are going to
add it, and you'll get notified then that it's disallowed.
