crecord: exit edition of hunk with non-zero status does not interrupt session

Before this patch, when editing a hunk, if the editor was exiting with a non-
zero status the crecord session would be aborted. This patch makes crecord
handle the failure and goes back to the state before the failed edition.
We use the new error reporting mechanism introduced in the previous patch to
notify the user of the issue.
