==================== Summary ====================

Name: FileAttributesPlugin.oscog-eem.56
Author: eem

Ancestors: FileAttributesPlugin.oscog-eem.55

Fix regression in FileAttributesPlugin>>primitiveFileMasks in Pharo images.  Only Squeak/Cuis can expect WordArray to be present in the specialObjctsArray.  Pharo is missing out on native support for the four widths of non-obhect array, but that's its perogative, and the Vm has to remain backward-compatible.  Mea culpa.
