saveOrReturn() raises an exception!

[cartbeforehorse]

I've just noticed that saveOrReturn() raises an exception if $throwValidationExceptions is set true. The documentation suggests that the whole purpose of this function is to avoid throwing an exception, even if the afore-mentioned variable is set. Also I extracted this comment from the code:

/** saveOrReturn()
 * Perform a one-off save that will return a boolean on
 * validation error instead of raising an exception.
