delta-find: move the emotion of parents in a dedicated method
After splitting the filtering, and with the `_candidate_groups` layer removed,
we can start splitting the group generation too. This helps to organize this
code and make it easier to modifying the future.
Testing recorded "modified" files for merge commit
==================================================
This file shows what hg says are "modified" files for a merge commit
(hg log -T {files}), somewhat exhaustively.
This test file shows merges that involves files contents changing
For merges taht involves executable bit changing, check test-merge-combination-exec-bytes.t
For testing of multiple corner case, check test-merge-combination-misc.t
Case with multiple or zero merge ancestors, copies/renames, and identical file contents
with different filelog revisions are not currently covered.
$ . $TESTDIR/testlib/merge-combination-util.sh
All the merges of various file contents.
