----------------------------------------
The following example shows that REXML is adding white space to the text property of elements when setting the :indent option on Document#write greater than -1. The value written should be the same value read.

~~~ruby
require 'rexml/document'

xml_string = ''

REXML::Document.new(xml_string).tap do |doc|
  doc.add_element('root').tap do |root|
    write_text = 'bar'
    puts "Write Text: #{write_text.inspect}"
    root.add_element('foo').text = write_text
  end
  
  doc.write output: xml_string, indent: 4
end

REXML::Document.new(xml_string).tap do |doc|
  read_text = doc.elements['/root/foo'].first
  puts "Read Text:  #{read_text.inspect}"
end

puts "XML String:"
puts xml_string
~~~

~~~text
Write Text: "bar"
Read Text:  "\n        bar\n    "
XML String:
<root>
    <foo>
        bar
    </foo>
</root>
~~~
