Indeed! An worst case example: in this buffer: --8<---------------cut here---------------start------------->8--- texttexttexttexttexttexttexttexttexttexttext --8<---------------cut here---------------end--------------->8--- (first and last line empty), M-0 beginning-of-buffer RET actually jumps to the end of the buffer. In large buffers, adding one rather makes a big difference to the result. So there doesn't seem to be so much witness in adding that summand... Michael.
