Also in jedi, Leia takes a hit to the arm. While painful for a period of time, she doesn't seem to have any lasting effects? Though we never actually see the wound itself, but during the end she gives Luke a big ol hug like nothing happened. (Though, this is possibly more story-based heroic healing rather than anything based on how this might actually effect people).
Hero healing, I would bet.
Also, the shot seems to be a glancing shot.
