RE: buff-menu.el header line

[Drew Adams]

    When `Buffer-menu-use-header-line' is nil, the header line generated
    by `list-buffers' fails to line up with the underlines.

Right. I reported the same bug on 10/16:

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.
