Okay, slowly getting there... stepping through carefully...

N.B. decode-coding-region is apparently C code.  Maybe some
funny structure sharing going on?

Before call to (decode-coding-region (point) msgend coding) 
[shown at *** below in rmail-redecode-body] :

  rmail-message-vector contains 3 markers at 1, 183, 1176
  (equal (aref rmail-message-vector 2) x-coding-header) => nil
  (point)  =>  223
  msgend [variable]  =>  1176
  coding [variable]  =>  iso-latin1-unix

result of call => "953"

After call:

  rmail-message-vector contains 3 markers at 1, 183, 223
  (equal (aref rmail-message-vector 2) x-coding-header) =>  t
  (point)  => 223
  msgend [variable] => 1176
  coding [variable] => iso-latin1-unix
