BTW `kill-append' is another one of these functions that end
with something that can be t or nil, from the on-line help it
says

  (kill-append STRING BEFORE-P)

  [...] If BEFORE-P is non-nil, prepend STRING to the kill
  instead

One can instead make the last argument optional, it then
defaults ot nil, instead of having ugly code that looks like
this

  (kill-append "This doesn't look good" nil)

where people have to check what that second argument nil
really is ...
