The output of `<f1> v TeX-master RET' now includes some byte-code:
,----[ <f1> v TeX-master RET ]
| TeX-master is a variable defined in `tex.el'.
| Its value is nil
|
| Automatically becomes buffer-local when set in any fashion.
|
| This variable is safe to use as a file local variable only if its value
| satisfies the predicate `#[(x) [BYTE-CODE stripped] [x (t nil shared dwim)]
2]'.
| [...]
`----
To reproduce:
- emacs -Q
- C-x C-f new-file.el RET
- insert...
--8<---------------cut here---------------start------------->8---
(defvar rs-foo nil)
(put 'rs-foo 'safe-local-variable
(lambda (x)
(or (stringp x)
(member x (quote (t nil shared dwim))))))
--8<---------------cut here---------------end--------------->8---
- C-x C-s
- M-x emacs-lisp-byte-compile-and-load RET
- <f1> v rs-foo RET
