[PATCH] ostruct.rb: recursive inspect, .send with exotic symbols, return value of assignment

Moin.

I've attached a patch for ostruct.rb (against 1.8.2, but I don't think 
there was changes to it lately) which makes the following work:

> irb(main):001:0> o = OpenStruct.new                      
> => #<OpenStruct>                                         
> irb(main):002:0> o.o = o                                 
> => #<OpenStruct o=#<OpenStruct ...>>                     
> irb(main):003:0> o.foo = "bar"                           
> => "bar"                                                 
> irb(main):004:0> o                                       
> => #<OpenStruct foo="bar", o=#<OpenStruct ...>>          
> irb(main):005:0> o.to_s                                  
> => "#<OpenStruct foo=\"bar\", o=#<OpenStruct ...>>"      
> irb(main):006:0> o.send(:"->=", "foo")                   
> => "foo"                                                 
> irb(main):007:0> o                                       
> => #<OpenStruct ->="foo", foo="bar", o=#<OpenStruct ...>>

It's mostly just small changes, but I think the recursive inspect is 
actually important. Making the inspect result more consistent with 
Object#inspect is probably also a good idea.
