Feature Request

• Yes, I reviewed the contribution guidelines.

When dealing with complex queries, WP Shell often dumps large volumes of data on to my screen.

For example, running a query with 'posts_per_page'=> 200, will result in hundreds of blog posts being printed. But I only want, say, the GUID.

Describe the solution you'd like

I'd like a command-line option so that wp shell --no-output will only display what I explicitly echo.

Current version:

wp shell
wp> $a = "hello";
=> string(5) "hello"

Proposed version:

wp shell --no-output
wp> $a = "hello";
wp>
