Piers Lauder, author of imaplib, emailed me the following comment about this bug:
------------
The regex for "mustquote_cre" looks bizarre, and I regret to say I can
no longer remember its genesis.
Note however, that the term CTL in the RFC definition for "atom-specials" means "any ASCII control character and DEL, 0x00 - 0x1f, 0x7f", and so maybe defining what is NOT an atom-special was considered easier.
The suggested replacement regex may not match these...?
-------------
It seems like we need to enumerate the control characters in the regex to be absolutely correct here.
