Manual 2.2.2 and 16.7 needs to amended

[Charles Millar]

I think the following changes are required: in the manual, if they 
already have not been made in the past few hours:

2.2.2
When Emacs first visits an Org file, the global state is set to
SHOWEVERYTHING, i.e., all file content is visible(1).

(No idea if the footnote needs to be changed.)

Likewise in section 16.7 the explanation for #+STARTUP, to wit:

responding variable for global default
settings is ‘org-startup-folded’ with a default value of ‘t’, which
is the same as ‘overview’.

needs amendment to reflect the current change in default visibility 
behavior.

Current version Org mode version 9.3.6 (release_9.3.6-619-g434940 @ 
/usr/local/share/org-mode/lisp/)

Best,

Charlie
