Out of curiosity: do you copy the nanorc across?  Or do you somehow
network mount it?

If those are the only machines that you use, then why not upgrade the
family Mac to nano-4.7 too?  Looking at your .nanorc, there aren't any
incompatibilities between 2.9.3 and 4.3 and 4.7, so only the 2.0.6 is
causing problems here, right?

But I'm guessing you are looking for a general solution that covers
all possible nano versions.  Well, then there isn't.  Nanos before
2.1.9 and after 2.8.7 don't know the --quiet option, so it is not
possible to skip and silence those warnings for all nanos.

Nano has evolved.  Some behaviors have changed (^W always searching
forward, for example) and some poorly-named options needed to be renamed.
I have knowingly sacrificed backward compatibility.  Sorry about that.
