Yes I am working on [2], the Idea I have to solve that bit is,
*Don't filter the reflective merge commit rev, rather merge it
differently by having separate editor hooks defined in the client/wc level.
Let us say
  - someone 'merge -r50:150 from /feature branch' to trunk working copy.
  - He already synchronized trunk to /feature branch and committed at r96
In issue-2897 branch code does 'merge -r50:95 from /feature branch' and
'merge -r96:150 from /feature branch', This looses changes from
  - local edits to resolve conflicts etc.
  - merge from some other source part of the same commit.
My thoughts on solving this further may be on issue-2897 branch or part
of some new issue branch.
  - Introduce the new boolean member 'is_reflective' to
'svn_merge_range_t'.
  - While populating 'remaining_ranges' populate this field when we
encounter a reflective revision
  - non_reflective_merge_editor which would analyze the given revision
number and do relevant non-reflective portions(adhoc local mods/merge
from some other source part of this commit)
  - 'merge -r50:95 from /feature branch'
  - Oh r96 is a reflective, Use non_reflective_merge_editor to merge the
non-reflective changes.
  - 'merge -r96:150 from /feature branch'
