Branch 1.3 created

[Grant Ingersoll]

OK, the 1.3 branch has been created.   General process for the next 7  
days is to go lightly even on trunk.  I don't know that we need to  
stop committing there, but keep in mind that we may have to backport  
patches between the two in the coming days.  As for the branch,  
blockers, doc updates, unit tests are all welcome, and the patch  
should, obviously, be applied to both trunk and the branch.

I will put  up an RC sometime today.  Since this is my first ever  
release, please bear with me as I work through the details.  Extra  
scrutiny is appreciated.

Cheers,
Grant
