Oh, no, I care very much: I go through great lengths to customize nano to my liking, to the point that I now inject code into it to construct my nanorc on-the-fly in memory for whichever version of nano it's running on: https://github.com/saagarjha/dotfiles/blob/master/fixnano.c (did you know that newer versions of nano can format your code and check if it compiles, displaying errors inline?). If I need to edit files and don't have it available I rely on vi being standardized by POSIX: https://pubs.opengroup.org/onlinepubs/9699919799/utilities/v...
