[bug-mailutils] MH's folder program

[djh]

Modifying mh-e lisp source code to handle mailutils output for cases when a 
folder does not exist as shown below. 

But, I still feel that the folder program should return a non-zero error code 
when errors or non-existing folders/directories occurr.  This should not be 
difficult to implement.  Do you want me to write a proposed patch for this?
