getGenerics is wrong in 1.8.0 alpha (PR#4184)

I have mentioned this several times, and it is still incorrect.  So I am 
submitting a formal bug report.

In 1.7.1 in a vanilla session

getGenerics(2)

An object of class "ObjectsWithPackage":

Object: "Arith" "Compare" "Complex" "Math2" "Math" "Ops"  "Summary"
From:   "base"  "base"    "base"    "base"  "base" "base" "base"

Object: "addNextMethod" "body<-" "coerce"  "coerce<-" "initialize" "loadMethod"
From:   "methods"       "base"   "methods" "methods"  "methods"    "methods"

Object: "show"
From:   "methods"

In 1.8.0 alpha (2003-09-16)

getGenerics(2)

An object of class "ObjectsWithPackage":

Object: "Arith" "Compare" "Complex" "Math2" "Math" "Ops"  "Summary"
From:   "base"  "base"    "base"    "base"  "base" "base" "base"

Object: "addNextMethod" "body<-"  "coerce"  "coerce<-" "initialize"
From:   "methods"       "methods" "methods" "methods"  "methods"

Object: "loadMethod" "show"
From:   "methods"    "methods"

body<- is incorrectly attributed to "methods", although it originates in 
base (whereas Compare, Complex and Math2 do not occur in base).
