Two-file merges were rare enough that they were dropped outside of the radar. This fix is a trivial change to builtin-rerere.c::find_conflict(). It is still sane to insist that we do not do rerere for symlinks, and require to have stages #2 and #3, but we can drop the requirement to have stage #1. rerere does not use information from there anyway. This fix is from Junio, together with two tests to verify that it works as expected.

The slings and arrows of outrageous fortune,

Or to take arms against a sea of troubles,

And by opposing end them? To die: to sleep;

No more; and by a sleep to say we end

The heart-ache and the thousand natural shocks

That flesh is heir to, 'tis a consummation
