+- Altough the standard enforces space-stuffing as a MUST, muttng
+ currently violates it. Space-stuffing is done once after initially
+ editing the message. The routine only handles '^From ' and '^ ' cases,
+ '^>' is ignored. (Once because an already space-stuffed line still has
+ a leading space so that it would get space-stuffed everytime the user
+ edits a message.)
