A refusal over unsaved panes keeps its list in +Unsaved and shows a short notice

Exit's refusal (and Restore's, Del's, Delcol's, get's) put its full text
on a notice that went: a long list of names, gone before it was read. The
list now goes into one +Unsaved pane, filled again by each refusal, a row
a pane (`<name>: Modified`) and the `Exit again to discard` line; the
notice is short, `3 unsaved panes — Exit again to discard`. The 9P
`unsaved` records and the write's err are as they were.
