How to abort an image edit?

[mehdid]

Reading the code, I see no way to abort an image edition if I wanted to (except backuping the old one, and then restore it). Am I missing something?

It might be because pty.spawn doesn't return the exit code of the command... Python 3.4 adds the necessary stuff to make this easier to implement. But maybe we can find another way until then to make this feature possible. (Like leaving around a file /tmp/plz_dont_touch_my_image in the image tree? :-P)

FWIW, before repacking the edited image, clara keeps the old image around adding ".old" to its name.
