Indents incorrectly for odd tab_size

[Quincunx271]

Beautify Ruby handles a tab-size of 2 very well, but when this is added to the preferences:

"tab_size": 3

Or any other odd number, for that matter, the indentation is completely wrong. As an example:

def test
   if false
      test do
         puts "incorrectly indented"
      end
   end
end

Becomes:

def test
    if false
      test do
          puts "incorrectly indented"
      end
    end
end

It doesn't indent each level at 3! It indents once at 4, then once at 2.

The exact issue is in lib/line.rb:

def tab_string
  indent_character * (indent_size / @tab_size ) + (indent_size.odd? ? ' ' : '')
end

As a temporary workaround, I'm changing that to

def tab_string
  indent_character * (indent_size / @tab_size ) # + (indent_size.odd? ? ' ' : '')
end

Why would we even want the + (indent_size.odd? ? ' ' : '')?
