8.5 Saving the Changed File

Traditional Unix diff3 generates an ed script without the trailing `w' and `q' commands that save the changes. System V diff3 generates these extra commands. GNU diff3 normally behaves like traditional Unix diff3, but with the `-i' option it behaves like System V diff3 and appends the `w' and `q' commands.

The `-i' option requires one of the ed script options `-AeExX3', and is incompatible with the merged output option `-m'.
