Re: archive-mode gets confused if two archives have the same filename

[Chris Moore]

That test case, involving 2 separate archives was overly involved.

The bug shows itself if you use a single archive:

1. make 2 directories:

  $ mkdip -p /tmp/dir1/dir

2. make 2 files:

  $ echo 111 > /tmp/dir1/file
  $ echo 222 > /tmp/dir1/dir/file

3. make a zip file

  $ cd /tmp/dir1; zip file.zip file dir/file

4. view the first file in the archive

  C-x C-f /tmp/dir1/file.zip RET f

5. it's fine; view the 2nd file in the archive

  C-x b RET n f

6. Emacs shows the first file ("111") not the 2nd file ("222")

This is on account of lisp/arc-mode.el constructing a buffer name like this:

  (let * ... (bufname (concat (file-name-nondirectory iname) " ("
arcname ")")) ...))

without stopping to worry that neither the file-name-nondirectory nor
the arcname are necessarily unique.
