bug#2222: 23.0.90; Labels in RMAIL

[jpff]

Could one not add a "fake" message at the start of the RMAIL file to
carry a list of all tags like in babyl?  The thing I had in mind would
be like the format used in pop, viz

> From MAILER_DAEMON  Thu Apr 26 18:16:43 2007
> Date: Thu, 26 Apr 2007 18:16:43 +0100
> From: Mail System Internal Data <MAILER-DAEMON@snout>
> Subject: DON'T DELETE THIS MESSAGE -- FOLDER INTERNAL DATA
> Message-ID: <1177607803@snout>
> X-IMAP: 1177607795 0000000097
> Status: RO
> 
> This text is part of the internal format of your mail folder, and is not
> a real message.  It is created automatically by the mail system software.
> If deleted, important folder data will be lost, and it will be re-created

Surely that would not be expensive and would allow a tag list to
remain, and possibly even carry the -*- rmail -*- stuff?
