wrap_in_html(): use strbuf_addstr_xml_quoted()

Browse source 
Use the new function to quote characters as they are being added to
buf, rather than quoting them in *p and then copying them into buf.
This increases code sharing, and changes the algorithm from O(N^2) to
O(N) in the number of characters in a line.
