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.
