[Bug 1694439] [NEW] Nano corrupts its buffer when adding newlines

[Jussi Lind]

Public bug reported:

Steps to reproduce
1) Open nano
2) Write, let's say, 10 lines of text. Content doesn't matter
3) Go to the beginning of, for example, line 5 and continue hitting enter

What should happen:
- New empty lines are added and the remaining lines are pushed down

What happens instead:
- Only a couple of new lines are added then the cursor just starts to move over the lines. Trying to add new lines now randomly sometimes works, sometimes doesn't. Usually the whole buffer gets messed up and also deleting lines does unexpected things
