Subject: 27.0.50; Flymake manual doesn't mention that syntax checking is
 started in after-save-hook
Date: Wed, 6 Jun 2018 21:57:29 +0200

The Flymake manual says that syntax checking is started whenever

- ‘flymake-mode’ is started, unless ‘flymake-start-on-flymake-mode’
     is nil;
- a newline character is added to the buffer, unless
     ‘flymake-start-syntax-check-on-newline’ is nil;
- some changes were made to the buffer more than ‘0.5’ seconds ago


But it doesn't mention that Flymake also starts in 'after-save-hook.
Also, I think there should be an option to disable checking the buffer
on save.

(add-hook 'flymake-mode-hook
  (lambda () (remove-hook 'after-save-hook 'flymake-after-save-hook t)))

But an option makes more sense.  Regarding the manual, you are also right.
I will do this for 26.2.
