Can you please explain the Merger.determineConflict function in more details?

[kuddai]

We have a merge bug in our code, given the following example
`
const strBase = '{"enabled":false}';
const strLeft = '{"enabled":true,"other":1}';
const strRight = '{"enabled":true}';
const merged = merge(strLeft, strBase, strRight);
assert.equal(merged.conflict, false,
'has no merge conflicts');

assert.equal(merged.joinedResults(), strLeft);

`

Output
actual: > {"enabled":truetrue,"other":1} expected: > {"enabled":true,"other":1}

This error steems from this line

As multiple intersected ranges from right are taken into final result. In our case the same 'true' token is taken several times from right array.
