This function marks @var{variable} (a symbol) automatically
buffer-local, so that any subsequent attempt to set it will make it
local to the current buffer at the time.
+Contrary to @code{make-local-variable} with which it is often confused, this
+cannot be undone, and affects the behavior of the variable in all buffers.
A peculiar wrinkle of this feature is that binding the variable (with
@code{let} or other binding constructs) does not create a buffer-local
