* encoding.c: fix the comment to describe the real return values * pattern.c xpath.c include/libxml/pattern.h: lot of work on the patterns, pluggin in the XPath default evaluation, but disabled right now because it's not yet good enough for XSLT. pattern.h streaming API are likely to be changed to handle relative and absolute paths in the same expression.
