I'm interested in your feedback on what errors should be thrown here. and below.

Thanks, these error values seem fine. What is the error message that ultimately gets sent to the operator? |

The error that is returned by server.DeleteMessage is sent to the operator (that is, err.Error()). However, while I was away I realized this PR will need to be refactored, because it breaks a situation in which persistent storage is storing a channel or user which is not currently logged in (which is the intention of the original code). Will get on this. |
If hist == nil and mysql database Delete msgid function returns ErrDBIsNil, we know that the target does not match any channel or user. Return invalid target error to operator (see ergochat#2020)

Fixes #2020
Calling /msg histserv delete #wrongchan returns spurrious success message. Calling /msg histserv delete returns similar message.
These would lead to the pointer hist == nil, and
server.historyDB.DeleteMsgid() would return nil.
Returns errNoSuchChannel or errInvalidTarget if channel or client == nil
