By not returning from inside the "if (pathspec)" block, we can let the
pathspec-aware and pathspec-less code share a bit more, making it
easier to make future changes that should affect both cases. This also
highlights the similarity between read_from_tree() and reset_index().
---
Should error reporting be aligned too? Speaking of which,
do_diff_cache() never returns anything by 0. Is the return value for
future-proofing?
