Revert "Merge branch 'en/merge-recursive'"

As the band-aid to merge-recursive seems to regress complex merges in an
unpleasant way.  The merge-recursive implementation needs to be rewritten
in such a way that it resolves renames and D/F conflicts entirely in-core
and not to touch working tree at all while doing so. But in the meantime,
this reverts commit ac9666f84 that merged the topic in its entirety.
