[PATCH v4 4/4] new: Unify add_files and add_files_recursive

[Austin Clements]

Since starting at the top of a directory tree and recursing within
that tree are now identical operations, there's no need for both
add_files and add_files_recursive.  This eliminates add_files (which
did nothing more than call add_files_recursive after the previous
patch) and renames add_files_recursive to add_files.
