bug#4075: 23.0.91; dired file name parsing incorrect when using TRAMP

Dired parses the file name incorrectly when using TRAMP if the name
begins with a date and is followed immediately by a space.

To reproduce:
1) Visit a file with the name pattern:
   C-x C-f /user@host:/tmp/2009-08-07 hello.txt RET

2) Enter text and save the file to create it
   hello
   C-x C-s

3) Invoke dired on the directory
   C-x C-d RET

4) Use 'n' and 'p' to navigate.  When landing on the file name created
above, note that point is positioned at 'hello.txt', not at the
beginning of the file name.

Value of directory-listing-before-filename-regexp was
".*[0-9][BkKMGTPEZY]? \\(\\(\\([A-Za-z']\\|[^
