merge: make 'diverging renames' diagnostic a more helpful note.

See the Hg Book on why we actually want to detect this case:
http://hgbook.red-bean.com/read/mercurial-in-daily-use.html#id364290

Before:

$ hg up deadbeef
warning: detected divergent renames of X to:
...

After:

$ hg up deadbeef
note: possible conflict - X was renamed multiple times to:
...

No functionality change.

test that a commit clears the merge state.

  $ hg init repo
  $ cd repo

  $ echo foo > file
  $ hg commit -Am 'add file'
  adding file

  $ echo bar >> file
  $ hg commit -Am 'append bar'


create a second head

  $ hg up -C 0
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ echo baz >> file
  $ hg commit -Am 'append baz'
  created new head

failing merge

  $ HGMERGE=internal:fail hg merge
  0 files updated, 0 files merged, 0 files removed, 1 files unresolved
  use 'hg resolve' to retry unresolved file merges or 'hg update -C .' to abandon
  [1]

  $ echo resolved > file
  $ hg resolve -m file
  $ hg commit -m 'resolved'
