hgweb: fix diffstat links in paper/changeset.tmpl

'<a .../>foo</a>' syntax is incorrect, since the first tag just "tries" to
close itself and then the actual content follows. It doesn't work, either
because web browsers know better than this or because there should be a
whitespace before /: '<a />'. So for the hgweb users the links looked
normal anyway, but now they are correct in code as well.

Tests if hgweb can run without touching sys.stdin, as is required
by the WSGI standard and strictly implemented by mod_wsgi.
