+Subject: [PATCH 2/3] Don't unnecessarily try to change a file context
+
+As pointed out by Tim Waugh here:
+
+  https://bugzilla.redhat.com/507555
+
+We shouldn't bother trying to set the context of a file if it already
+matches what we want.
+
+(Fixed to use STREQ() and not use tabs, as pointed out by danpb)
