10 | * - no-attr + ';' 3 * num_attr (e.g. "22;") | |
11 | * - fg color + ';' 17 (e.g. "38;2;255;255;255;") | |

13 | * - terminating 'm' NUL 2 | |

15 | * The above overcounts by one semicolon but it is close enough. | |
16 | * | |
17 | * The space for attributes is also slightly overallocated, as | |
18 | * the negation for some attributes is the same (e.g., nobold and nodim). | |
19 | * | |
20 | * We allocate space for 6 attributes. | |
