7 * The maximum length of ANSI color sequence we would generate:
8 * - leading ESC '[' 2
9 * - attr + ';' 2 * num_attr (e.g. "1;")
10 * - no-attr + ';' 3 * num_attr (e.g. "22;")
11 * - fg color + ';' 17 (e.g. "38;2;255;255;255;")
12 * - bg color + ';' 17 (e.g. "48;2;255;255;255;")
13 * - terminating 'm' NUL 2
15 * The above overcounts by one semicolon but it is close enough.
17 * The space for attributes is also slightly overallocated, as
18 * the negation for some attributes is the same (e.g., nobold and nodim).
20 * We allocate space for 7 attributes.
