Actually, to restore a deleted file there is a command 'vc-revert'.
Obviously it can't be called on a deleted file or its buffer
because it's already gone.  But it can be used on a line
with the tag "removed" in the vc-dir buffer.  There is
no shorter vc-dir binding to this command, so the global keybinding
'C-x v u' could be used on the vc-dir line with the removed file.
This completely reverses the deletion.
