** Minibuffer changes
-*** Operations like C-x b and C-x C-f, which use switch-to-buffer, do
-not fail any more when used in a minibuffer or a dedicated window.
-Instead, they fallback on using pop-to-buffer, which will use some
-other window.

*** When M-n in the minibuffer reaches the end of the list of defaults,
it adds the completion list to the end, so next M-n continues putting
completion items to the minibuffer. The same principle applies to
region in transient-mark-mode, the word under the cursor, the last Isearch
regexp, the last Isearch string and the last replacement regexp.
+*** When enable-recursive-minibuffers is non-nil, operations which use
+switch-to-buffer (such as C-x b and C-x C-f) do not fail any more when
+used in a minibuffer or a dedicated window. Instead, they fallback on
+using pop-to-buffer, which will use some other window. This change
+has no effect when enable-recursive-minibuffers is nil (the default).

*** Isearch started in the minibuffer searches in the minibuffer history.
Reverse Isearch commands (C-r, C-M-r) search in previous minibuffer
history elements, and forward Isearch commands (C-s, C-M-s) search in
