There is only a current folder from the nmh perspective, not from the
perspective of another program trying to access something in the nmh
directory structure.

What you have above doesn't quite do the trick.  I guess that I will
agree with you that this can be done without a change to mhpath though.

        folder_name=`mhparam Current-Folder`

        if [ $? -ne 0 ]; then
                echo "No current folder."

                folder_path=`mhpath +$folder_name`

                if [ -d "$folder_path" ]; then
                        echo "Current folder is $folder_name."
                        echo "No current folder."

Pretty cumbersome.  Takes more code that the change to mhpath would
