the paragraph here gives some useful details: https://www.gnu.org/software/emacs/manual/html_node/elisp/Undo.html#index-undo_002dauto_002damalgamate
this means emacs will group together a certain number of inserted characters into an atomic unit; it's that unit which is undone by the
undo
command. if you want character-by-character undo then you will need to tell emacs to not perform this grouping. one thing to try would be to add advice to theinsert-char
function to set that undo boundary for you upon each keystroke; I'm sure there are other ways to do this as well.The following paragraph from what you quote has the heavy handed approach whereby no changes are amalgamated and undo would work character by character.
