This isn't a bug, but would it be worth a sentence on the `stack[512] = {}`
initializer? With the new one-record-per-line format the legacy
`stack depth %511s max %ld` branch never fires, so the trailing strtok_r()
loop would otherwise run over an uninitialized buffer - that seems worth
calling out in the changelog rather than leaving it to be inferred from the
diff.
