Title:
  cp fails with filenames ending in backslash

Status in rust-coreutils package in Ubuntu:
  New

Bug description:
  upstream bug https://github.com/uutils/coreutils/issues/8739

  Although uncommon and probably unwise, linux filenames can end in slash.
  uutils-coreutils appears to wrongfull intrepret those as directories and fails copying.

  This currently breaks tests some lintian tests.

  repro:

  # cp -V
  cp (uutils coreutils) 0.2.2
  # mkdir a
  # touch a/foo\\
  # cp -r a b
  cp: 'b/foo\' is not a directory
  # ls -la b
  total 1
  drwxr-xr-x 2 root root 2 Sep 24 23:07 .
  drwx------ 6 root root 9 Sep 24 23:07 ..
