Documentation
Strip special properties from the message buffer.
Emacs has a number of special text properties which can break message composing in various ways. If this option is set, message will strip these properties from the message composition buffer. However, some packages requires these properties to be present in order to work. If you use one of these packages, turn this option off, and hope the message composition doesn't break too bad.
This variable was added, or its default value changed, in Emacs 22.1.
