[bug-mailutils] Is this a bug?

[djh]

Gnu Mailuitls Program name: folder


Example:
  $ /usr/local/bin/mu-mh/folder -fast -nocreate +inbox
  inbox
  $ echo $?
  0

That looks right. I do have a directory "inbox".

But, 
  $ /usr/local/bin/mu-mh/folder -fast -nocreate +mhe-index
  mhe-index
  folder: Cannot open context file /home/henman/mail/mhe-index/.mh_sequences: 
No such file or directory
  $ echo $?
  0

Shouldn't the return code be a non-zero value? 
Since I don't have a +mh-index directory in $MAIL as confirmed below:

  $ ls `mhparam Path`/mhe-index
  $ ls: /home/henman/mail/mhe-index: No such file or directory
  $ echo $?
  2
