When nil Buffer-menu-use-header-line, column headings don't sort (and get error)

[Drew Adams]

emacs -q

(setq Buffer-menu-use-header-line nil)

C-x C-b

1. The column headings have mouse-face highlighting, and they should
   sort the columns when you click them, but they don't. Instead, you
   get this error: No buffer on this line. The key sequence of mouse-2
   on a column heading is bound to `Buffer-menu-mouse-select'.

2. The second line in the buffer is used to underline (with "---") the
   column headings of the first line, but the underlinings don't line
   up with the column headings. The first line (headings) starts with
   a space, but it should not. The first line does not line up with any of
   the other lines.
