Does Deno's FsFile.readable automatically close the file when the stream is exhausted?

Given the following code:

const file = await Deno.open(fsPathname, { read: true })
return new Response(file.readable, { status: 200 })

Will FsFile.readable automatically close the file once the stream has been exhausted? The documentation doesn't mention this. If the answer is 'no' then I don't see how you close the file without seriously unneeded complexity.

Yes, the file resource associated to its readable stream will be closed when the stream encounters EOF.

The documentation is currently lacking, but a PR has been created to improve this and also to add an option to prevent closure of the file resource if desired.
