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
