7 * The maximum length of ANSI color sequence we would generate:
8 * - leading ESC '[' 2
9 * - attr + ';' 2 * 8 (e.g. "1;")
10 * - fg color + ';' 9 (e.g. "38;5;2xx;")
11 * - fg color + ';' 9 (e.g. "48;5;2xx;")
12 * - terminating 'm' NUL 2
13 *
14 * The above overcounts attr (we only use 5 not 8) and one semicolon
15 * but it is close enough.
