It was not a faulty commit since you followed the rule stated in the
developer's manual, as Thomas just pointed out. ;-}
Let's note that the manual is not always up-to-date; but in this particular
case, the difficulty is compounded because we don't all have the same
feeling about this rule.
I'd just say that we should not add systematically the exceptions to the
signature. Those who like it would do it in the code they often contribute
to, hopefully not cluttering the code which they don't have to test very

Best regards,

[1] And by the fact that the exception debate has generated so much
discussion in the past 18 months that I didn't want to write a document
about the new exceptions, that would be irrelevant a few weeks later...
