FILE_STATUS_* not being used as a binary flag in system_cron()

The comment for FILE_STATUS_* flags says that it should be binary flags with the first 8 bits reserved. I can see that the first two are 0 for TEMPORARY and 1 for PERMANENT which might have been old status when it was a boolean instead of a binary flag. On line 1227 of the system.module within system_cron() there is a SQL query that is used to get all temporary files over a certain time to delete them. The SQL query is doing a straight status = %d when it should be doing a bitwise operator. Attached is a patch to do that. Unfortunately I am not sure if anything needs to be changed for the file_set_status() function within the file.inc. From my understanding that file_set_status() should be a bitwise OR instead of a straight up assignment. Reasoning for this is that the original comment for the FILE_STATUS says that contrib modules could create their own status. Well if two modules have different status flags and they don't know about each other then they should only really be setting the bits that they care about and leaving the other bits to whatever the other contrib modules have set for that file.
