FYI, I looked at these.

I fixed paste15 and assert2.  I will fix up the test cases and check
in my patch after regtesting, and after yours goes in (I'll need the
dg fix).

The pr28165 case is funny because the tokens come from a string.  At
first glance libcpp is not set up to handle this gracefully.  I'll dig
a bit more.
