Thanks, a few minor comments about the documentation parts:

Our style is to describe the "normal" case first.  Like this:

  Normally, the copied file names are relative to the current buffer's
  default directory, but you can control that with the prefix
  argument.  With prefix argument of zero, the file names are copied
  in their absolute form; with any other value of prefix argument, the
  file names are relative to the root directory of the VCS repository.

This basically repeats the same text as above.  We usually first
describe the command in short, preferably in one sentence, and place
the detailed description further down.  Please try to follow these
conventions.
