debug-discovery: deal with case where common is empty

This code was previously confused by case where:

    `heads_common == {nullid}`

===================================================================
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
