'a_type' was just a made up example, it can be any valid token, say
'g_file', or whatever.  I was pointing out a disparity in handling of
some token in c-ts-mode and tree-sitter: tree-sitter identifiers a 6
byte length token as an identifier, but c-ts-mode requires it to be
at least 11 byte sized for custom types.
