[PATCH] "@" is not recognized as part of defun name for emacs-lisp

[PATCH] "@" is not recognized as part of defun name for emacs-lisp

[Jérôme Marant]

Hi,

It is seem that @ is a valid character in function names (although
I did not see any place in the Lisp Ref where valid characters are mentioned.
I guess everything but parentheses would be the answer?)

Lisp-mode does not properly highlight function names containing
such a character.

    A symbol name can contain any characters whatever. Most symbol
    names are written with letters, digits, and the punctuation
    characters `-+=*/'. Such names require no special punctuation; the
    characters of the name suffice as long as the name does not look
    like a number. (If it does, write a `\' at the beginning of the
    name to force interpretation as a symbol.) The characters
    `_~!@$%^&:<>{}?' are less often used but also require no special
    punctuation. Any other characters may be included in a symbol's
    name by escaping them with a backslash.

I found it. Thanks.
