/**
* Justin Adie says:
* method to fix inconsistent use of quoted, unquoted etc date values in query function
* this is ironic, given the above rewrite badlyformed dates method
* examples
* Fix the date string and quote. This is required for the calendar widget.
*
* where month(fieldname)=08 becomes month(fieldname)='8'
* where month(fieldname)='08' becomes month(fieldname)='8'
*
* I don't understand...
* I use preg_replace_callback instead of 'e' option because of security reason.
* cf. PHP manual (regular expression)
*
* @return void
