Buffer-menu-buffer-column's default value of 4 is hard-coded into several
functions from buff-menu.el. As of 24.0.50, this is true of
Buffer-menu-sort and Buffer-menu-revert-function.
This is not strictly speaking a bug, but it is an anti-pattern, and it can
unexpectedly bite someone hacking on buff-menu.el. So it would perhaps be
good practice to make the following changes:

Just a quick follow-up: After posting the bug report I noticed the same
problem in Buffer-menu-buffer+size. In the display spec
(space :align-to ,(+ 4 name+space-width)
at the end of the function, that "4" should also be replaced with
"Buffer-menu-buffer-column".
