When I want to compose a new email, Mutt will prompt for the recipients
("To:"), followed by the subject ("Subject:"). How do I disable the
prompting for the subject? The `autoedit` configuration option will not
help here because it disables both prompts (i.e. both "To:" and
"Subject:"). I only want to disable the "Subject:" prompt. How can I do
this in Mutt?
