Perhaps I am not reading what the option does correctly, but my
understanding is that merge operations:

 - always allow rerere to intervene and auto-resolve in the working
   tree, as long as rerere is enabled;

 - by default they however do not add the rerere-resolved result to
   the index, so that the combined diff output from "git diff" can
   be used as a way to sanity check the result; but

 - if the user says --rerere-autoupdate, they add the
   rerere-resolved result to the index, letting the user blindly
   trust it, so that such a trusting user can even commit the result
   without looking at it by merely making sure there is no path
   remaining in the "git ls-files -u" output.  

The "autoupdate" could be somewhat dangerous depending on your
workflow, and that is why the user can selectively enable it via the
command line option (when known to be safe) even if the user does
not set rerere.autoupdate to true.

So I am not sure I understand "an option to allow something to be
done automatically should not be given manually" as a valid argument
at all, whether it is weak or strong.

Or am I grossly confused?
