Minor nits: sections 10.2.1.1, 10.2.1.2

[Jim Blandy]

In section 10.2.1.1, "Declarative environment records", the first 
paragraph has an extra comma before "and/or function declarations".  
There are only two alternatives there, so no comma is necessary.

In section 10.2.1.2, "Object Environment Records", the second sentence 
begins, "An environment record binds...".  I believe that is meant to 
say, "An object environment record binds..." since the statement is not 
true of all environment records.
