Subject: 24.2; [PATCH] wrong regexp in c-basic-matchers-before

From: Leo <[email-masked]>

It seems to me this regexp in c-basic-matchers-before would never
succeed unless @ is of word syntax.

(concat "\\<"
        (regexp-opt
         '("@interface" "@implementation" "@protocol")
         t)
        "\\>")

Should this patch be applied?
