Subject: [PATCH] Use EDITOR environment variable

When preferences do not specify a program to be used for /editor
command, try getting it from EDITOR (which POSIX.1-2017 calls one of
"variables that are frequently exported by widely used command
interpreters and applications"), fall back to "vim" if not set.
