dired.el regex not matching spaces before file names

[Daniel Ortmann]

This bug report will be sent to the Free Software Foundation,
 not to your local site managers!!
Please write in English, because the Emacs maintainers do not have
translators to read other languages for them.

In GNU Emacs 20.7.1 (rs6000-ibm-aix4.3.3.0, Motif)
 of Mon Nov 20 2000 on neon.rchland.ibm.com
configured using `configure  
--prefix=/afs/rch/rel/common/prod/ct/local/200011/rs_aix43 --with-x 
--with-x-toolkit=motif'

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

I've reported this bug before and (I think) I was told it was fixed in the new
version.  Perhaps the fix was applied to a different version?

In the following lines from a dired buffer note the extra whitespace before
the "37R00B9_data" filename:

  -rwxr-xr-x   1 ortmann  ortmann     3410 Oct 23 13:49 .login.runpsp
  -r--r--r--   1 ortmann  ortmann    39466 May 05 2000  37R00B9_data

This extra whitespace causes emacs to be unable to recognize the file when I
press "v" for "visit".

The following patch to some regex in dired.el seems to fix the problem for me.
It should, of course, be reviewed for general safety and utility:
