mod_pastebin: Fix pasting when <body> is not the first tag (thanks thorsten) Introduced in ded630a87563 stanza:get_child() and :get_child_text() operates on the first child when no name or namespace is given. If it so happens that the first child is an <thread/> instead of <body> then it calculates the line length against that instead of the body. Apparently in the vast majority of clients the <body> is first, so this issue was not noticed until now.
