This works just like @code{write-file-hooks}, but it is intended for
hooks that pertain to the contents of the file, as opposed to hooks that
pertain to where the file came from. Such hooks are usually set up by
major modes, as buffer-local bindings for this variable. Switching to a
new major mode always resets this variable.
major modes, as buffer-local bindings for this variable.
This variable automatically becomes buffer-local whenever it is set;
switching to a new major mode always resets this variable. When you use
@code{add-hooks} to add an element to this hook, you should @emph{not}
specify a non-@code{nil} @var{local} argument, since this variable is
used @emph{only} locally.
