emitrevision: if we need to compute a delta on the fly, try p1 or p2 first

Falling back to `prev` does not yield any real value on modern storage and
result in pathological changes to be created on the other side. Doing a delta
against a parent will likely be smaller (helping the network) and will be safer
to apply on the client (helping future pulls by Triggering intermediate
snapshop where they will be needed by later deltas).

===================================================================
Test merge behavior with narrow for item outside of the narrow spec
===================================================================

This test currently check for  simple "outside of narrow" merge case. I suspect
there might be more corner case that need testing, so extending this tests, or
replacing it by a more "generative" version, comparing behavior with and without narow.

This the feature is currently working with flat manifest only. This is the only
case tested. Consider using test-case if tree start supporting this case of
merge.

Create some initial setup

  $ . "$TESTDIR/narrow-library.sh"

  $ hg init server
  $ echo root > server/root
  $ mkdir server/inside
  $ mkdir server/outside
  $ echo babar > server/inside/inside-change
  $ echo pom > server/outside/outside-changing
  $ echo arthur > server/outside/outside-removed
  $ hg -R server add server/
  adding server/inside/inside-change
  adding server/outside/outside-changing
  adding server/outside/outside-removed
  adding server/root
  $ hg -R server commit -m root



  $ hg clone ssh://user@dummy/server client --narrow --include inside

"trivial" change outside of narrow spec on the server

  $ echo zephir > server/outside/outside-added
  $ hg -R server add server/outside/outside-added
  $ echo flore > server/outside/outside-changing
  $ hg -R server remove server/outside/outside-removed
  $ hg -R server commit -m "outside change"

Merge them with some unrelated local change

  $ echo celeste > client/inside/inside-change
  $ hg -R client commit -m "inside change"
  $ hg -R client pull
