branch: master
commit c8d638ac9db02291e221c0c5f18ce28be3084a50
Author: Arash Esbati <>
Commit: Arash Esbati <>

    Use `functionp' to recognize a function
    * tex.el (TeX-parse-argument): Identify a function with
    `functionp' instead of `symbolp'.  This way it is also possible to
    use a closure inside a style hook.
