 Sorry, I forgot to mention about "with-editor"'s actual usage and the
 expected result.
 
 "with-editor"'s actual command is the following.
 https://github.com/magit/with-editor/blob/v2.8.3/with-editor.el#L174-L180
 ```
 $ sh -c 'echo "WITH-EDITOR: $$ OPEN $0  IN $(pwd)"; sleep 604800 &
 sleep=$!; trap "kill $sleep; exit 0" USR1; trap "kill $sleep; exit 1"
 USR2; wait $sleep'
 ```
 And it expects exit code provided by "exit" in "trap".
 That is, exit code 0 if "sleep" is killed by "USR1" signal. And exit
 code 1 if "sleep" is killed by "USR2" signal.
 
 For the simplified version in the original report, exit code 0 is
 expected when "sleep" is killed by "TERM" signal.
