Use `message-replace-header' instead of low-level functions.

,----[ <f1> f message-replace-header RET ]
| message-replace-header is a compiled Lisp function in `message.el'.
| (message-replace-header HEADER NEW-VALUE &optional AFTER FORCE)
| 
| Remove HEADER and insert the NEW-VALUE.
| If AFTER, insert after this header.  If FORCE, insert new field
| even if NEW-VALUE is empty.
