merge: warn about file deleted in one branch and renamed in other (issue3074)

For divergent renames the following message is printed during merge:
note: possible conflict - file was renamed multiple times to:
 newfile
 file2

When a file is renamed in one branch and deleted in the other, the file still
exists after a merge. With this change a similar message is printed for mv+rm:

note: possible conflict - file was deleted and renamed to:
 newfile
