 We're consensus-driven and I don't want to give an impression of rushing 
things in.  I hate it when some people do this.  I think a settling period 
of 24-48 hours is appropriate in cases like this, in case someone wants to 
chime in.

 This was missing a ChangeLog entry, which I have now added, and committed 
this change.  Thank you, Fredrik, for your contribution!
