Log message:
        (mh-folder-list): Fix problem with passing in a folder and getting
        nothing back. Fix problem with passing in empty string and getting the
        entire filesystem (or infinite loop). Don't append slash to folder.
        These fixes fix problems observed with the pick search. Thanks to
        Thomas Baumann for the help (closes SF #1435381).
