how to make it default so that nano wraps lines at 80 columns

Dear All,

Please CC me as I have turned off replies to the ML as I am hopelessly
information-overloaded.

I have been trying to get nano to wrap as user (not as root) at an
arbitary length of 80 columns on Debian stretch . Some details of the
package are as under -

┌─[shirish@debian] - [~] - [4190]
└─[$] nano --version

 GNU nano, version 2.7.1
 (C) 1999..2016 Free Software Foundation, Inc.
 (C) 2014..2016 the contributors to nano
 Email: [email protected]	Web: https://nano-editor.org/
 Compiled options: --disable-libmagic --disable-wrapping-as-root --enable-utf8

┌─[shirish@debian] - [~] - [4234]
└─[$] realpath .nanorc

/home/shirish/.nanorc

┌─[shirish@debian] - [~] - [4235]
└─[$] cat .nanorc

set autoindent
set backup
set constantshow
set fill 80

Sharing a simple text file see

as well as a screenshot as what it is doing at the moment. Using ESC +
L gives a wrapping at 137 columns but dunno by what logic it is doing
that. I am writing an essay/article using nano and have to manually
adjust things.

Look forward to know the correct way to do things.
