Some user agents deliberately generate non-standard
message identifier lists in In-Reply-To and References headers.
Instead of failing silently, aerc now falls back to a desperate parser
scavaging whatever looking like <id-left@id-right>.
As the more liberal parser being substituted with, References header
are now stored for IMAP not only when there's a parsing error.
