I think we're discussing the default behavior when electric-indent-mode is on, 
which it often is by default.

I too was taken aback and annoyed by the new behavior of C-o.  For example, I 
visited src/lisp.h and typed this:

C-s xnmalloc C-a C-o

The resulting buffer looked like this:

   extern void *xrealloc (void *, size_t) ATTRIBUTE_ALLOC_SIZE ((2));
   extern void xfree (void *);
   X
                                 extern void *xnmalloc (ptrdiff_t, ptrdiff_t) 
ATTRIBUTE_MALLOC_SIZE ((1,2));
   extern void *xnrealloc (void *, ptrdiff_t, ptrdiff_t)
     ATTRIBUTE_ALLOC_SIZE ((2,3));

(where the cursor is marked with "X"), i.e., the "xnmalloc" line was greatly 
indented, which is not what I wanted.  With old Emacs it would look like this:

   extern void *xrealloc (void *, size_t) ATTRIBUTE_ALLOC_SIZE ((2));
   extern void xfree (void *);
   X
   extern void *xnmalloc (ptrdiff_t, ptrdiff_t) ATTRIBUTE_MALLOC_SIZE ((1,2));
   extern void *xnrealloc (void *, ptrdiff_t, ptrdiff_t)
     ATTRIBUTE_ALLOC_SIZE ((2,3));

which is what I wanted: a new blank line with the cursor at the start, and with 
no change to the next line.
