How would you decide that if you cannot read the information that is
presented to you?

Can you tell without thinking for 10 seconds which of these two changes is
lost if you choose "Use local version"?

@@@ ... @@@
  x
 +foo
  y
@@@ ... @@@
  a
- bar
  b

Oh, it's easy for the conflicted part of the diff, which you'll see
elsewhere as well:

@@@ ... @@@
  r
++<<<<<<< HEAD
 +foo
++=======
+ bar
++>>>>>>> some-branch
  s

Do not forget that in a case (like mine) where the non-condensed diff is
actually huge, the conflict markers would no exactly be easy to find in
the diff.

And I was saying almost the same, namely that it should not only be "much
more likely" to pick c, but to *always* pick c (by making it the only
option available).

And therefore I suggest to disable these options.

Which are those very simplest cases that you are referring to? If you mean
modify/delete conflicts, then I indeed would like to keep the options for
them.

That said, your earlier patch that presented the diff against HEAD was not
bad after all.
