I'm considering creating a patch for storing Gmail labels for
type=Gmail. For the Maildir format, where could I store the label data
for each message? I'm not super familiar with the Maildir format but
it seems to me that labels should be handled similarly to flags, but I
don't think it's a good idea to store labels in the filename of each
message. Does the Maildir format allow for mutable data to be stored
in the file itself?
