Here's an update to the list of buffer local variables. Most are new to Emacs
22 (fill-prefix and font-lock-defaults are two exceptions. I guess the notion
of standard is a bit arbitrary but I've roughly assumed if that if it's
mentioned in the manual then it's standard. If some of the variables that
I've added aren't appropriate then I'll move then to the @ignore section at
the end so that, in future, everyone can see that their omission is deliberate.
To clarfiy the concept of buffer local variables for myself:
In gdb-ui.el (as in many other files, I often just copy current practice), I
have constructs like
(set (make-local-variable 'font-lock-defaults)
'(gdb-memory-font-lock-keywords))
but I could just do
(setq font-lock-defaults '(gdb-memory-font-lock-keywords))
?

In gdb-ui.el (as in many other files, I often just copy current practice), I
have constructs like
(set (make-local-variable 'font-lock-defaults)
'(gdb-memory-font-lock-keywords))
1. It is always cleaner to use separate calls to make-local-variable
and setq.
2. When the variable is automatically local, it is ok to
delete the call to make-local-variable. A major mode
normally doesn't set any variable that isn't local.

That's not true. *You* may always find it cleaner, but it's far from
a general truth. E.g. I strongly prefer to keep the two together (actually
I'd like to introduce a setq-local macro for it).

I think that separate calls are always cleaner.
You're entitled to your opinion, of course.

I guess if the make-local-variable and setq get separated then it might
not be immediately obvious that the variable is buffer-local.
However, my original question was that with a variable like
font-lock-defaults, that automatically becomes buffer-local in each buffer, I
presumably don't need to use make-local-variable at all?

That's only true if you're 100% sure that the call to
make-variable-buffer-local will always have been made before your code runs.
In the case of font-lock-defaults it's currently true (since it's in
font-core.el which is preloaded), but it wasn't true in older Emacsen.
