"".constantize returns Object

#6432

Not 100% sure if this should be considered a bug, but I found it a bit unexpected and it masked a bug in a project I was working:

ruby-1.9.2-p136 :001 > "".constantize
 => Object 
ruby-1.9.2-p136 :003 > "".constantize == ::Object
 => true

I expected an error, as if I had done:

ruby-1.9.2-p136 :008 > Object.const_get("")
NameError: wrong constant name

I'm still not sure this is a bug - the default receiver in global namespace is Object and the existing code does take into account the possibility of an empty names array. I'll ask Jeremy Kemper since he wrote the original code.
