The reason for this behaviour is really very simple to explain -
there was a bug in the library :-) (xinclude.c, now fixed in CVS).

The option XML_PARSE_INCLUDE is only used by the xmlTextReader
interface, and has no effect when used with xmlReadFile or
xmlParseFile (you can easily check this by doing a "grep
XML_PARSE_INCLUDE *.c" in the library source directory).

Try the modified source from CVS - several other problems with
xinclude have also been fixed.  It seems to work okay for me:
bill billsuper list $ ./curious source.xml
<?xml version="1.0"?>
<element xmlns:xi="http://www.w3.org/2003/XInclude";>
   <element>what's up, Doc?</element>
</element>
