Bug #5915: Array#join with explicit nil should not use $,
https://bugs.ruby-lang.org/issues/5915#change-28176

Author: john_firebaugh (John Firebaugh)
Status: Closed
Priority: Normal
Assignee: naruse (Yui NARUSE)
Category: DOC
Target version: 2.0.0
ruby -v: ruby 1.9.3p0 (2011-10-30 revision 33570) [x86_64-darwin10.8.0]


=begin
The documentation for Array#join says that the default argument is $,. But:

  $, = ","
  [1,2,3].join(nil) #=> "1,2,3"

Based on the documentation (and the POLS), I would expect "123".
