* lib/rexml/formatters/pretty.rb (REXML::Formatters::Pretty#wrap):

Browse source 
REXML::Formatters::Pretty#wrap used a recursive method call to
  format text.  This switches it to use an iterative approach.
  [ruby-core:33245]
  Patch by Jeremy Evans. Thanks!!!

* test/rexml/test_core.rb: add a test for it.
