Is "are not supported" the right phrasing? I think it makes perfect sense not to forbid "!path attr1", because it is unclear what it means (e.g. "path -attr1" vs "path !attr1"). So I would say "Negative patterns are forbidden as they do not make any sense". But for the latter, I think it makes a lot more sense to just accept "path/ attr1" and doing nothing. The user requests to set an attribute to "path" that has to be a directory, and there is nothing wrong in such a request in itself. But nothing in git asks for attributes for directories (because we do not track directories), and such a request happens to be a no-op.
