If we're going to start having mediaCheckFile return extra codes instead
of just zero and non-zero, we should add #defines to libcheckisomd5.h to
give these codes names. That'll help insulate anaconda from potential
future changes a bit.
Enter seems a little weird for an abort key stroke. Is there a reason
you picked that over escape, ctrl-d, or something else that users might
already be familiar with?

Ah, I see, you're not really just looking for enter so much as you're
looking for any keystroke. Probably fine then.
