Hi Isaac,
what do you mean, in config.inc.php? We do not offer this file in the
download kit. Do you mean the generated config.inc.php via setup? or the
sample config file?

Indeed we should do what PHP expects and use NULL; and I suggest that
the user doc tell the truth (config.default.php contains NULL). The doc
should give a clear example when a value other than NULL needs to be used.
