Add git-update-cache --replace option.
When "path" exists as a file or a symlink in the index, an attempt to add "path/file" is refused because it results in file vs directory conflict. Similarly when "path/file1", "path/file2", etc. exist, an attempt to add "path" as a file or a symlink is refused. With git-update-cache --replace, these existing entries that conflict with the entry being added are automatically removed from the cache, with warning messages.
