ZF-1206: Zend_Filter_RealPath to support non-existing paths
I would like to suggest to add an enhancement to the current Zend_Filter_RealPath filter. PHP's function realpath will give you the absolute path from the provided path, however this does not work when a path does not exist. Realpath would then return false.
Allowing calculation of realpath() results when the input path does not exist, would be a good enhancement for the current implementation.
However, the developer should be able to turn this feature on/off, as I can imagine the need of having false returned when the path does not exist.
