Thanks, Tony. This is why I looked at `:scriptnames` — to be sure that defaults.vim wasn't affecting what I was seeing. So, rather than the observed behaviour being different to what I expected, it was my reading of the documentation that was wrong.

This is confusing.

When the :help says "Vim default: …, set in defaults.vim", we don't really know what the real default is. Using 'showcmd' as an example, if I create a vimrc that contains only "set wrap", and run `vim`, 'showcmd' is off — the real default, which isn't mentioned in `:help 'showcmd'`.
