The rules for the extension are the same as Perl's (see perldoc perlrun): if the extension includes no ``*'' then it is appended to the original file name, If the extension does contain one or more ``*'' characters, then each ``*'' is replaced with the current filename.
If this option is used the XML declaration is updated (and created if there was none).
Make sure that the encoding is supported by the parser you use if you want to be able to process the pretty_printed file (XML::Parser does not support 'latin1' for example, you have to use 'iso-8859-1')
This prevents a bug (see BUGS) but uses more memory
