Subject: bug#524: outdated (put ...) exceptions for evaled file-local variables
Date: Thu, 03 Jul 2008 15:44:53 +0900

[Message part 1 (text/plain, inline)]

Currently `hack-one-local-variable-eval-safep' has a few
manually checked exceptions for the `eval' pseudo-variable,
so that the common cases of setting indent and edebug
properties for symbols is considered safe automatically.

However, the indent property checks for `lisp-indent-hook',
which as far as I can tell is deprecated.  It's not
mentioned anywhere in the docs, and lisp-mode.el only uses
it as a fallback in case the `lisp-indent-function' property
isn't set.  All the properties in lisp-mode.el are set as
`lisp-indent-function'.

A simple fix would be to allow either.  I've attached a
potential patch that does this, and also allows
scheme-indent-function, since this case is also common and I
don't think there are many other modes that make use of
symbol indent-function properties.  I'd understand if you
didn't want to support Scheme by default though, in which
case I'd just resort to using `safe-local-eval-function'.

A more general fix might be to implement a separate
customization for which properties are automatically
settable with which values, with perhaps more broad default
settings than Emacs currently has.
