POSTing XML input confuses siege

[petriborg]

Any XML POST inputs will confuse siege. Example: siege -c 1 -r 1 -g "http://testsrv/ POST <?xml version='1.0' encoding='UTF-8'?><foobar/>"

This happens because siege will only look at the '<' character, and try to process the rest of the line as a filename. Issue is in ./src/url.c __parse_post_data(URL this, char *datap).

The following can help fix the issue by looking for the XML declaration.
