exit with 0 or 1, as is proper. errno is an int, but the return value on a shell can be e.g. byte, and depending how that number (errno) is valued, could overflow and cause a zero exit, where you want a non-zero exit. the code has been changed, in such a way to maintain current behaviour (don't change errno), except that when errno is set upon exit, the exit value is now one.
