I've been trying to understand the sdiff source code in order to
figure out why it does this, but to no avail.  I'm usually very good
at debugging, but this one has me stumped...

athene:tih> cat > foo
a
b
c
d
e
athene:tih> cat > bar
a
x
c
y
e
athene:tih> sdiff -o baz foo bar
a                                                               a
b                                                             | x
%l
c                                                               c
d                                                             | y
%r
e                                                               e
sdiff: subsidiary program `ed' failed
athene:tih> cat baz
a
b
c
y
e

It works just fine, but returns an error anyway.  (Another problem
with it is that it needs ed, but heeds the EDITOR environment variable
anyway, so you have to make sure that's not set.)
