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
