I've tried the C-M-h command at the beginning of a very simple buffer in
c-mode.

The first time i use de command, the first "defun" is selected, but when i
repeat the command more times, nothing happens, but there are more defun's
after the first one!!

This is my c-mode buffer:

-------------------------
int f1()
{
  return 1;
}


int f2()
{
  return 1;
}
-------------------------

So, Why i can't select f2 when i run the C-M-h command several times in a
row?
