    Diagnose and correct defective umask
    
    A too-restrictive corporate customization of umask has caused too many
    difficult-to-diagnose problems. Override it with the usual default value
    to prevent those problems. Complain whenever it is encountered, so that
    the offending file in /etc/ can be fixed.
