/* A conservative bound on the maximum length of a human-readable string.
The output can be the square of the largest uintmax_t, so double
its size before converting to a bound.
- 302 / 1000 is ceil (log10 (2.0)). Add 1 for integer division truncation.
+ log10 (2.0) < 146/485. Add 1 for integer division truncation.
Also, the output can have a thousands separator between every digit,
so multiply by MB_LEN_MAX + 1 and then subtract MB_LEN_MAX.
Append 1 for a space before the suffix.
Finally, append 3, the maximum length of a suffix. */
