Summary: php-53 throws substr warning on every page if LANG is unset

Initial Comment:
If you leave LANG blank in the config.ini (the default) and you are running php-53, there's a php warning thrown on every page:

Warning: "substr() expects parameter 3 to be long, string given"

I'm running the phpwiki-1.4.0 from svn trunk as of 2/20/12.

Specifying an explicit LANG fixes this, but the config.ini comments indicate a blank entry is valid.
