Comment 1 for bug 73337

My EDITOR environment variable is not set, so sdiff tries to use 'ed' (which I've also got installed) and the message I'm getting after running:

  sdiff -o diff.txt diff1.txt diff2.txt

and doing a merge is the following:

  sdiff: subsidiary program `ed' failed

funnily enough, the merge seems to work regardless of the error message.
