I wonder why we set up this knob this way. A lot of operating systems support fopen(..., "r") of a directory --- wouldn't it make sense for FREAD_READS_DIRECTORIES to be the default and for users on stricter platforms to be able to set FREAD_DOES_NOT_READ_DIRECTORIES if they want to speed Git up by taking advantage of their saner fread?

Thanks, Jonathan
