Test of (lack of) comment preservation by inlining,
whether by literalization or reduction.

Comment handling was better in an earlier implementation
based on byte-oriented file surgery; switching to AST
manipulation (though better in all other respects) was
a regression. The underlying problem of AST comment fidelity
is Go issue #20744.
