unpack-trees: simplify 'all other failures' case
In the 'if (current)' block of twoway_merge, we handle the boring
errors by checking if the entry from the old tree, current index, and
new tree are present, to get a pathname for the error message from one
of them:
if (oldtree)
return o->gently ? -1 : reject_merge(oldtree, o);
if (current)
return o->gently ? -1 : reject_merge(current, o);
if (newtree)
return o->gently ? -1 : reject_merge(newtree, o);
return -1;
Since this is guarded by 'if (current)', the second test is guaranteed
to succeed. Moreover, any of the three entries, if present, would
have the same path because there is no rename detection in this code
path. Even if some day in the future the entries' paths differ, the
'current' path used in the index and worktree would presumably be the
most recognizable for the end user.
Simplify by just using 'current'.
