The 'unzip' program exits with error code (because it prints warnings,
to stderr) when it processes .ja files. That's why MC fails. Here's
what to do:

(1) Create a wrapper for unzip (and make it executable):

    #!/bin/sh
    if echo "$* " | grep "\\.ja "; then
      # when dealing with .ja files, suppress warnings and error code.
      unzip "$@" 2>/dev/null
      exit 0
    else
      exec unzip "$@"
    fi

(2) Edit /usr/lib/mc/extfs.d/uzip. Tell it to use the wrapper instead
of "/usr/bin/unzip".

You can also do "cd omni.ja/uzip://". (Or symlink it. Or edit MC's
"extension file".)
