ser 1d8c98a486 Merges upstream changes for REXML v3.1.7
http://www.germane-software.com/repos/rexml/tags/3.1.7

 r1278@bean:  ser | 2007-06-07 00:53:06 -0400
 Fixed a double-encoding bug.  This was a regression, related
 to ticket:48.
 r1292@bean:  ser | 2007-07-25 08:19:36 -0400
  r1279@bean:  ser | 2007-06-09 23:19:02 -0400
  Fixes ticket:89 -- encoding CP-1252 was broken.  ISO-8859-15 had the same
  problem.
  
  Also in this patch is a fix to merge.rb (unused, but it should at least
  contain no errors), and a unit test for ticket:88.

  Addresses ticket:85
  
  This is a major rewrite of the XML formatting code.  The XML writers have all
  been extracted out of the classes and put into their own class containers.
  This makes writing parsers easier, and cleaner.
  
  There are three formatters, which correspond to the previous three XML writing
  modes:
  
    REXML::Formatters::Default    
        Prints the XML document exactly as it was parsed
    REXML::Formatters::Pretty     
        Pretty prints the XML document, destroying whitespace in the document
    REXML::Formatters::Transitive 
        Pretty prints the XML document, preserving whitespace
  
  All of the write() functions have been deprecated (some are still used, but
  these will also go away) except the write() function on Document, which is left
  for convenience.  To pretty print an XML document the canonical way:
  
    formatter = REXML::Formatters::Pretty.new( 5 ) # indent by 5 spaces
    formatter.write( document, output )

  r1283@bean:  ser | 2007-07-24 19:53:30 -0400
  This goes with the previous commit.
 
 r1295@bean:  ser | 2007-07-25 08:19:39 -0400
  r1285@bean:  ser | 2007-07-24 20:02:07 -0400
  And THIS goes with the previous two patches.  Dammit.
 
 r1296@bean:  ser | 2007-07-25 08:19:40 -0400
  r1287@bean:  ser | 2007-07-24 20:12:25 -0400
  Applied patch from Jeff Barczewski.  Note that this changes what the values of
  the name and IDs are from the previous behavior -- the values no longer include
  the quotes.  This is the correct behavior, so I'm leaving it in, but it is not
  backwards compatible.  Also fixes the serializer so that it outputs the doctype
  in a correct format (needed as a result of this change).
