Thanks.  I'll fix the whitespace problem and commit it to the trunk 
momentarily.

If it weren't for the C++ template aspect I probably would "just know".

Hmm, if there's some you think ought to be closed, feel free to comment 
on them and pass along their IDs.  I can review and close as appropriate.

Or I can ask around and find out what the current procedure is for 
getting you more privileges in bugzilla.  Your call on that.

As for when the shift occurs to bugfixing, it's usually in early/mid 
November each year.  That also happens the be the deadline for 
development patches to have been posted for review, hence most folks are 
busy trying to wrap up their development work.
