A refusal over unsaved panes logs each as `unsaved <serial> <name>`, and its err never cuts a list

Exit's refusal joined every name into one err, cut at the record's cap in
mid-name, so a script could not tell which panes held it up. Each pane is
now an `unsaved` record before the err, and the err names the one pane
or counts them: `4 unsaved panes: Modified (Exit again to discard)`.
Restore, Del and Delcol refuse the same way.
