Grep with no hit says grep: no match, and a pane directory that is not there is passed over

Grep walks every pane's directory; one not there (a scratch named into a
directory not made yet) failed the whole search with `file not found`.
Such a root is passed over now, and a search that finds nothing says
`grep: no match` and opens no empty +Search.
