"zed delete" doesn't create a detailed log message

[philrz]

Repro is with Zed commit cdd9d06.

Other commands like load and revert include details in the log, whereas delete just shows the commit ID. Not sure how detailed we'd want to get, but at minimum it seems it would be helpful to mention it was a delete, and perhaps also the object IDs, or deleted record count & -where filter if applicable.
