Thanks.  Looks good.  Will apply it to master tomorrow.

I will drop the references to the other two bugs (that I added) because
the patch doesn't prevent that the original file remains truncated when
the target device is full and under concurrent writing pressure.

(The patch just reduces the severity of such a truncation because nano
will have saved a copy of the original file to the user's home directory.
But that will be a small consolation when the file is some configuration
file that must be there for some system to function.)
