Unfortunately it seems that I'm mistaken:
- Open an existing *.gpg file
- do M-x epa-file-select-keys and select some keys
- do any change, so that saving is possible (a problem on its own, as
  changing the list of recipients should be considered a relevant change
  it self)
- C-x C-s leads to an error:

So is there any comfortable way at all to change the list of recipients?
