(defun dired-ui-dired-copy-filename-as-kill (&optional arg)
  "Copy name of file at point into the kill ring.

This function works the same as `dired-copy-filename-as-kill' but
adds the prefix option \\[universal-argument] to copy file name
up to the project root as determined by `project-root'.

The behaviour of \\[universal-argument] is changed from the
original function, where it used to copy up to the default
directory of the current buffer, which in case of inserted
subdirectories was the \"main\" directory."
