http://redmine.ruby-lang.org/issues/show/1251

Author: Alexander Pettelkau
Status: Open, Priority: Normal
Category: core, Target version: 1.9.1
ruby -v: ruby 1.9.1p0 (2009-01-30 revision 21907) [i386-darwin9.6.0]

I wanted to replace "\" with "\\" in the string "\TEST":

s="\\TEST"
puts s    # Output --> "\TEST"
s.gsub!("\\","\\\\")
puts s    # Output --> "\TEST"
          # but EXPECTED Output "\\TEST"
