Heh. I had no idea we had FREAD_READS_DIRECTORIES. I think Duy and I

You two were not alone.  I was planning to reinvent it before I went
to bed last night and then found it already was there this morning ;-)

I agree that may be worth setting on Linux (though note that we _do_
ignore other stdio read errors in the rest of the code path, which may
be something we want to address).

Yes, we need an error check on fopen() in git_config_from_file()
regardless.
