[Bug 1866820] [NEW] crash in nano-4.8 when typing ^6 ^J [patch]

[Benno Schulenberg]

Public bug reported:

Nanos since version 4.0 contain a silly oversight: when the user tries
to justify an empty region (with ^6 ^J, or similar), nano crashes.

Attached upstream patch fixes the problem.  Please apply to Focal before
it is released.
