Bytes written to the command's standard input, when it had any.

Part of the key, not just the record: `load-buffer -` is the same command
whatever it is fed, so a recording keyed on the commands alone would
answer a test that wrote different bytes with the ones it first saw, and
a regression that corrupted a buffer would replay as a pass.
