File comment is lost when removing first statement

If you have

/**
 * @providesModule Foo.react
 */

var React = require('React');

and remove the require statement, the docblock is lost. This causes build errors and I had to manually fix up a bunch of files with the last codemod I wrote to restore these.

@fkling What are your thoughts on adding a recipes section to the documentation (similar to this). I’ve found a few examples of use-cases in the past digging through the issues on this repo that would have been great to have documented.

I know there are already links to the codemod repos in the bottom of the readme, but specific recipes could be an added bonus.

What is the rationale to attach comments to other nodes? Why can’t they live as independent nodes?
