cmd/gofmt: update TestRewrite to avoid future regressions

CL 162337 changed go/ast to better handle block comments,
but was reverted because it introduced an off-by-one bug.
This CL adds a test case to enforce the correct behavior
so that future changes do not break this again.

Updates #18929
Updates #33538
