[kaiwk]

What were you expecting?

In *Messages* buffers, don't appear the following warning:

Multiple snippets with same identity: "transform"
Multiple snippets with same identity: "generate_n"
Multiple snippets with same identity: "remove"
Multiple snippets with same identity: "<<"
Multiple snippets with same identity: "copy"
Multiple snippets with same identity: "c["
Multiple snippets with same identity: "transform"
Multiple snippets with same identity: "generate_n"
Multiple snippets with same identity: "remove"
Multiple snippets with same identity: "<<"
Multiple snippets with same identity: "copy"
Multiple snippets with same identity: "c["
Multiple snippets with same identity: "transform"
Multiple snippets with same identity: "generate_n"
Multiple snippets with same identity: "remove"
Multiple snippets with same identity: "<<"
Multiple snippets with same identity: "copy"
Multiple snippets with same identity: "c["

What actually happened?

Looks like there are duplicate snippets in c++-mode.
