A builtin's Verbose announcement is logged only when it succeeds

A failure said while it ran (Exit's refusal, a Del refused) or later by
the host (a Save's write, a Dump's) left `msg N Save` in the log as if it
had worked. The announcement's record is remembered and taken back out
on either, unless a follower read it already. A refused pane/new logs its
err alone, and a failed Dump says its reason in words (`file not found`,
not `FileNotFound`) so its msg goes and the err is the one record.
