+;; Because `super-save-mode' automatically saves every time we move away from a
+;; buffer, it tends to run a lot of `before-save-hook's that don't need to be
+;; run that often.  For that reason, I'm writing a mode where C-x C-s saves
+;; /and/ runs all the "real" before-save-hooks, so that super-save won't
+;; automatically do things like format the buffer all the time.

+This function is precisely the same as `save-buffer', but with
+one modification: it also runs functions in `user-save-hook'.
+This means that if you have some functionality in Emacs to

+to automatically run when the buffer saves that are
+computationally expensive or just aren't something you want to
