split: handle partial commit of renames when doing split or record (issue5723)

When using split or record, using either interface (text or curses), selecting
portions of the file to be committed/recorded did not work; the entire file was
treated as having been selected. This was because the logic for handling partial
application of the patches relies on knowing what files are "new with
modifications" and it doesn't treat "rename destination" as "new".

There was a complicating issue, however. We're relying on the patch header
specifying the copy from/to information, which works as long as the 'copy from'
file is there. In the case of renames, however, the 'rename from' file is *not*
there, so we need to add it back.
