Re: patch for dired-format-columns-of-files

(Sorry, I didn't write about the bug as I thought it is clear that what
 is it. But, I should have written it.
 In accordance with auto reply e-mail, I have already sent to
 171@emacsbugs.donarmstrong.com. But just to make sure, I will send to
 bug-gnu-emacs@gnu.org again.)

For example, I find the bug after I do (dired-do-flagged-delete), if
`FILES' list includes Japanse file name. The bug is that each file name
doesn't separate properly in "*Deletions*" buffer.
Because (dired-format-columns-of-files) uses `length' function not
`string-width' function. So, I corrected it.

example:

      d:/test:
      total used in directory 0 available 1024
      drwxrwxrwx   1 user root             0 05-01 12:22 .
      drwxrwxrwx   1 user root             0 1970-01-01  ..
    D -rw-rw-rw-   1 user root             0 05-01 12:22 test.txt
    D -rw-rw-rw-   1 user root             0 05-01 12:22 テスト.txt
    D -rw-rw-rw-   1 user root             0 05-01 12:22 テスト2.txt
    D -rw-rw-rw-   1 user root             0 05-01 12:22 テスト3.txt

  (dired-do-flagged-delete)
  => (in "*Deletions*" buffer)
