Label information isn't propagated to mail files

[rom]

When I first labeled a message as important, its X-Mozilla-Status2 attribute (header) changed from 00000000 to 02000000. However, setting the label back to nothing, didn't update the attribute in the mail file. It was evidently stored in .msf file. This is bad because there's sometimes a need to delete .msf files and have them recreated. But if the .msf files store label info, it would be lost when the .msf file is deleted. Mail files should be completely autonomous, IMO.

Closing and restarting Minotaur and even compacting the folder didn't help.
