The problem is that git, like most source code control systems, interprets
any non-zero return from the user's editor as a commit failure.  
On the other hand, since ed is often used non-interactively, it's
important that it report any failure of a script through the exit
status, so that shell scripts can notice what's happened.

The best approach is to use this script as the value of $EDITOR:

ed "$@"
exit 0

That forces the exit value always to be 0, no matter what happens inside
the editor.
