write_file: add format attribute
This gives us compile-time checking of our format strings, which is a good thing. I had also hoped it would help with confusing write_file() and write_file_buf(), since the former's "..." can make it match the signature of the latter. But given that the buffer for write_file_buf() is generally not a string literal, the compiler won't complain unless -Wformat-nonliteral is on, and that creates a ton of false positives elsewhere in the code base. While we're there, let's also give the function a docstring, which it never had. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
