Make !pattern in .gitattributes non-fatal
Before 82dce99 (attr: more matching optimizations from .gitignore, 2012-10-15), .gitattributes did not have any special treatment of a leading '!'. The docs, however, always said The rules how the pattern matches paths are the same as in `.gitignore` files; see linkgit:gitignore[5]. By those rules, leading '!' means pattern negation. So 82dce99 correctly determined that this kind of line makes no sense and should be disallowed. However, users who actually had a rule for files starting with a '!' are in a bad position: before 82dce99 '!' matched that literal character, so it is conceivable that users have .gitattributes with such lines in them. After 82dce99 the unescaped version was disallowed in such a way that git outright refuses to run(!) most commands in the presence of such a .gitattributes. It therefore becomes very hard to fix, let alone work with, such repositories. Let's at least allow the users to fix their repos: change the fatal error into a warning.
