Description

Some of the snippets look like this:

'#ifndef ${1:SYMBOL}\n#define $1\n\n${2}\n\n#endif /* end of include guard: $1 */\n'

I think you are supposed to use:

'#ifndef ${1:SYMBOL}\n#define $1\n\n$0\n\n#endif /* end of include guard: $1 */\n'

But I think this won't make a difference in Atom currently, since Atom doesn't implement the exact same behavior that TextMate has for $0. In TextMate & VS Code, $0 changes the final cursor position after you press tab on the final tab stop. If you have a snippet without $0 than the final tab press will move the cursor after the snippet. In Atom, the cursor will be left on the last tab stop when there isn't a $0 instead of moved to the end of the snippet.
