Does warn for what? Array with known size? Sure, so it should - you
have excess initializer list elements.

Note the [] in the quoted - it does matter.

Again, it's perfectly legitimate to use string literal to initialize
any kind of array of character type. \0 goes there only if there's
space for it; if array size is unknown, the space is left. That's it.
