It seems that this had been fixed in Ruby 1.9.3. Please update your ruby or request a backport for r31997 and r31998. (ayumin will backport them. :-) See also #4498.

----------------------------------------
Bug #5892: REXML always wraps long tag text regardless the page width setting.
https://bugs.ruby-lang.org/issues/5892

Author: Dimitri Geshef
Status: Rejected
Priority: Normal
Assignee: Kouhei Sutou
Category: lib
Target version: 1.9.2
ruby -v: ruby 1.9.2p180 (2011-02-18) [i386-mingw32]


When ones prints a REXML document that contains a tag with a long text (with space chars), the REXML::Formatters::Pretty formatter will force a line wrapping at column 80.
If one changes the value of the width attribute of the formatter to a very large value does not change the result.
In other words, the formatter ignores the value of the 'width' attribute.
The REXML version used is:
  REXML VERSION = "3.1.7.3"
  REXML REVISION = 26193 

Apparently, the defect lies in the method REXML::Formatters::Pretty#write_text.
There is a statement with a hardcoded value of 80.
Look in the .rb file in attachment for a possible fix of this bug.
