I don't know what kind of input can produce such an output.
When I run `diff --side-by-side --suppress-common-lines' it returns:

  foo1 | bar1
  foo2 | bar2
  foo3 | bar3
  foo4 <

Writing a script that replaces " | " with "< " and " >" you can get:

  < foo1
  > bar1
  < foo2
  > bar2
  < foo3
  > bar3
  < foo4

that is not equivalent to a normal diff output that groups adjacent lines
into diff hunks like:

  < foo1
  < foo2
  < foo3
  < foo4
  > bar1
  > bar2
  > bar3
