I just redirect the output to /dev/null.  There is a folder
-noprint, currently undocumented.  All it does now is allow
output of the folder stack while suppressing other output.
Maybe change it to suppress all output?

That could cause confusion if there was nothing else in
.mh_sequences:

    /*
     * If no mh-sequences file is defined, or if a mh-sequences file
     * is defined but empty (*mh_seq == '\0'), then pretend folder
     * is readonly.  This will force all sequences to be private.
     */
    if (mh_seq == NULL || *mh_seq == '\0')
        set_readonly (mp);

The workaround for now would be to set cur: to something that
isn't a message.  `mhpath new` will give you one, but as a
full path.  "cur: 0" seems to work.

But we really should come up with an interface to do that.
folder -clearmessage?  Or folder -clear, but that seems like
it should clear the current folder, too.
