11013	"file_descriptor_sink won't create a file in ""app"" mode"	Josh Kelley <joshkel@…>	Jonathan Turkanis	"When file_descriptor_sink(filename, ios::app) is used on Linux, it refuses to create the file if the file doesn't already exist.

This is inconsistent with std::ofstream's behavior with ios::app, and it's inconsistent with file_descriptor_sink's behavior on Windows (where it does create the file if it doesn't exist).
