   "Control if changes proposed by LSP should be confirmed with user.
 
 If this variable's value is the symbol `diff', a diff buffer is
-popped up, allowing the user to apply each change individually.
-If the symbol `summary' or any other non-nil value a short
-summary of changes is presented to the user in a
-minibuffer-prompt.  The symbols `maybe-diff' and `maybe-summary'
-are also accepted and mean that the confirmation is presented to
-the user if the changes target visited files only.  A nil value
-means the change is applied directly to visited and non-visited
-files, without any confirmation.

-If this variable's value is a list, it should be an
-alist ((COMMAND . ACTION) ...) where COMMAND is a symbol
-designating a command, such as `eglot-rename',
-`eglot-code-actions', `eglot-code-action-quickfix', etc.  ACTION
-is one of the symbols described above.  The value `t' for COMMAND
-is accepted and its ACTION is the default value."
