Good catch, fixed.

"outdent" is the more proper word here.
Afaik programmers invented "dedent", e.g.
https://docs.python.org/3/library/textwrap.html#textwrap.dedent

I found "dedent" more obvious and used it enough since that I've
forgotten it's not really a word.

It's not really a concern here, but I'm always wary given python has
significant whitespace.
I've seen enough instances of moved code where the indentation wasn't
properly updated.
