mc creates file of zero length instead of extracting file from mkisofs-created iso images containing Joliet without RockRidge extension
Steps to reproduce:
- create iso image with Joliet but without RockRidge
mkisofs -J -o test.iso /etc/passwd
- run
/usr/libexec/mc/extfs.d/iso9660 copyout test.iso passwd passwd
Expected non-zero size passwd file, got file of zero size
The image created by mkisofs doesn't contain versions in filenames unlike images created by Nero 7 (windows). The bug was probably introduced with #2471
for mkisofs-generated image:
$ isoinfo -J -l -i test.iso

The simple solution would be replacement of iso9660 vfs with u7z. As bonus 7-zip can read iso images created by deepburner and winoncd 3.6 (they are Joliet with UCS level 1) and images created with mkisofs without -R and -J options at all
