merge: extract _resolvetrivial() function We would eventually like to move the resolution of modify/delete and delete/modify conflicts to the resolve phase. However, we don't want to move the checks for identical content that were added in 902554884335 (merge: before cd/dc prompt, check that changed side really changed, 2014-12-01). Let's instead move these out to a new _resolvetrivial() function that processes the actions from manifestmerge() and replaces any false cd/dc conflicts. The function will also provide a natural place for us to later add code for resolving false 'm' conflicts.

  $ hg init

  $ echo 123 > a
  $ hg add a
  $ hg commit -m "first" a

  $ mkdir sub
  $ echo 321 > sub/b
  $ hg add sub/b
  $ hg commit -m "second" sub/b

  $ cat sub/b
  321

  $ hg co 0
  0 files updated, 0 files merged, 1 files removed, 0 files unresolved

  $ cat sub/b 2>/dev/null || echo "sub/b not present"
  sub/b not present

  $ test -d sub || echo "sub not present"
  sub not present
