[PATCH 0/5] refactor unpack-trees

unpack-trees is a central file needed for the understanding of working tree manipulation. To help with the understanding refactor the code to be more readable.

The first patch was a standalone patch 8 days ago; now incorporated into this series as a v3, reducing the scope of the checkout state.

The second patch removes a single continue statement; it needed some digging to explain, but looks trivial.

The last 3 patches shorten the check_updates function by adding more functions. If we ever want to parallelize file IO then these smaller functions would be the scope to do it, keeping the check_updates as a high level function guiding through the steps what is happening during a working tree update.

Thanks, Stefan
