The change merged into Jiff
The buffers for printing durations fit the longest values: a negative ISO 8601 duration takes 36 bytes, not 35, and the friendly format counts the plus sign too, so printing no longer panics.
What it taught us
The longest written form of a value is not always at the end of its range: here it was a negative duration with the longest hour count and two-digit minutes and seconds. A fixed buffer size has to be derived from the format and checked with a test on the longest value.
