A crash when libxml2 returned NULL nodeset result was fixed. "-" was being confused with --elif. The generated XSLT now contains the namespaces extracted from the first input file. -N is once again allowed after other options. Namespace values were being registered as prefixes. A segfault is avoided when asked to move namespace nodes. There was a missing newline in the ed --help message. The test scripts portability was improved. XML_SAVE_WSNONSIG is only used if libxml is version 2.7.8 or later.
