It looks like the doc string of save-excursion contains a few typos:
Before Emacs 25.1, ‘save-excursion’ used to save the mark state.
To save the marker state as well as the point and buffer, use
^^^^^^ ^^^ ^^^^^^
‘save-mark-and-excursion’.
Shouldn't that be: "To save the mark state as well as point and the
buffer"?
