What to do with trailing "(was: <old subject>)" in subject lines.
If nil, leave the subject unchanged. If it is the symbol ask, query
the user what to do. In this case, the subject is matched against
message-subject-trailing-was-ask-regexp. If
message-subject-trailing-was-query is t, always strip the trailing
old subject. In this case, message-subject-trailing-was-regexp is
used.
This variable was added, or its default value changed, in Emacs 24.1.
