In this instance, nothing. However, the '(...) form leaves it's
arguments unevaluated (quoted), while (list ...) evaluates them. Since
0, nil and -1 all evaluate to themselves there is no difference in this
case. However, the following two statements are different:
(list 0 fill-column -1)
'(0 fill-column -1)
A good place to start learning is the Introduction to Programming in
Emacs Lisp, which is available from gnu.org, if it isn't already present
in your info directory (i.e., C-h i m emacs lisp intro <ret>).
HTH,
Tyler
