    todo: use bsdgrep on FreeBSD
    
    It looks like it supports all the options we use, where as GNU grep on
    FreeBSD is outdated and lacks --exclude-dir support.
    
    No need to add a setting for this, since I doubt FreeBSD will remove
    bsdgrep even when they update GNU grep (if they do).
    
    #361
