I think this batch of changes means we can turn
#allowUnderscoreSelectors on by default.

Looking through the senders of #numArgs, I noticed that many of them
were messages to  a selector. In those cases, the selector might
contain underscores, even though the preference disallows them, so I
made Symbol>>numArgs behave differently than String>>numArgs.

Unless somebody objects, I'll move these to the trunk soonish.
