Rob Pike d0652e7f82 cmd/doc: add test
Refactor main a bit to make it possible to run tests without an exec every time.
(Makes a huge difference in run time.)

Add a silver test. Not quite golden, since it looks for pieces rather than the
full output, and also includes tests for what should not appear.

Fixes #10920.
