 /* 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.  */
