bug#64355: 29.0.91; Should there be a command to delete a register?

[Drew Adams]

There has never been such a command, and you can simply set an existing
register to a new value, so arguably there's no need for a delete
command.  But it might be clearer for users if they could explicitly
delete a register, so it didn't show up in preview lists etc.

I suggest we choose the simpler option: no change.

Let's not add commands merely for symmetry's sake.

I tend to agree with Richard, especially seeing that we have no use case
for this.  I'm therefore closing this bug report.
