2498 Emacs has a number of special text properties which can break message
2499 composing in various ways. If this option is set, message will strip
2500 these properties from the message composition buffer. However, some
2501 packages requires these properties to be present in order to work.
2502 If you use one of these packages, turn this option off, and hope the
2503 message composition doesn't break too bad."
