It also doesn't work on remote VFS (such as fish, ftpfs) under X.  Also 
xdvi will exit when MC terminates.

- mc will be able (hopefully) to set up a separate process group in the
child and do whatever else is needed to prevent X programs from exiting
when mc exits.

Very good idea.  Thank you.  I think XView and XEdit would be useful too.  
I'm a bit hesitant about applying it now, but if it fixes (well, works 
around) the problem with the second %f not being expanded by VFS and 
doesn't introduce any new bugs, it will be applied.
