Building using brew on OSX generates 12,192 "not allowed" .gitattributes messages

[cjheath]

The following two-line message appears 12,192 times when building rust from source using "brew install --HEAD rust":

[attr]rust text eol=lf whitespace=tab-in-indent,trailing-space,tabwidth=4
not allowed: /private/tmp/rust-9Vuk/.gitattributes:1

It seems to cause no harm, other than obscuring any genuine messages.

Triage. Does this still happen? I don't have a Mac OS X machine.

I don't have an OSX machine either. Given the lack of commentary, I'd be willing to be it doesn't happen, but it'd be nice to know.

I've built rust with brew recently and this no longer happens.

Ok, feel free to reopen if this still happens!
