Documentation of Project Coin features as implemented in the JDK 7 developer preview

[Joe Darcy]

Hello.

As noted in subsequent discussion, the "diamond operator" isn't really 
an operator and we have taken to not referring to it as such.  For 
consistency, I think it is fine to allow (but discourage) extra white 
space between the "<" and ">" characters of a diamond.  I find this 
similar to the allowable white space between  the "@" and type name of 
an annotation.

Cheers,

-Joe
