Description

=begin
Terribly minor, but three warnings for the same problem is slightly excessive:

 run@paint:~ →  ruby -ve '_ = /\x/'
 ruby 1.9.3dev (2010-07-03 trunk 28530) [i686-linux]
 -e:1: invalid hex escape
 _ = /\x/
    ^
 -e:1: Invalid escape character syntax
 _ = /\x/
    ^
 -e:1: syntax error, unexpected $end

=end
