Which ones disappeared for you?  None did for me AFAICT (see below).

I see 1128 and 1779 lines on current master.  Diffing the *Help*
buffers, it seems to be a lot of stuff like this:

+C-x 8 ` SPC    `
+C-x 8 ` A      À
+C-x 8 ` E      È
+C-x 8 ` I      Ì
+C-x 8 ` O      Ò
+C-x 8 ` U      Ù
+C-x 8 ` a      à
+C-x 8 ` e      è
+C-x 8 ` i      ì
+C-x 8 ` o      ò
+C-x 8 ` u      ù

But when I run "emacs -Q" and immediately type C-x 8 ` A, I get the À
character as above (even though C-h b wouldn't have shown it in this
state).  If I type C-h b _after_ that sequence that yields 1779 lines
in *Help*.

I guess this has something to do with autoloading, but I'll leave this
to the experts.

Best regards,
Stefan Kangas
