Style/OpMethod should not complain about the backticks method

[donv]

Given the following code:

def `(cmd)
  system cmd
end

Rubocop complains with the following offence:

my_class.rb:40:7: C: Style/OpMethod: When defining the  operator, name its argument other`. (https://github.com/bbatsov/ruby-style-guide#other-arg)
def `(cmd)
      ^^^

I think that "other" is not an intuitive parameter name for the backticks method and that Rubocop should not report it as an offence.

$ rubocop -V
0.41.2 (using Parser 2.3.1.2, running on jruby 2.3.0 java)
