[PATCH 1/2] Keep signature delimiters intact in notifications

[Lukas Fleischer]

Since commit eeaa1c3 (Separate text from footer in notification emails,
2020-01-04), information about unsubscribing from notifications is added
in a signature block. However, the code to format the email body trimmed
the RFC 3676 signature delimiter, replacing "-- " by "--". Fix this by
adding a special case for signature delimiters.
