"""Pin the RFC-3676 "-- " signature delimiter fold for self-closing breaks.
|
|
|
|
_foldSignature folded the standard "-- " sig delimiter only when the
|
|
surrounding line breaks were the literal `<br>`; the regex missed `<br/>`
|
|
and `<br />` (what Apple Mail and many clients emit), even though the very
|
|
next matcher in the same function already uses `<br\\s*/?>`. So a plain-text
|
|
signature delimiter with self-closing breaks was never folded.
