bug#17307: 24.3.90; find-dired

[xaos52]

----

The regular expression `ls-regexp' does not match any line produced by
`find <directory> -ls'
Not on my system anyway, which is gnu/linux Debian sid.

The function is supposed to pad the 'number of blocks' and 'size' fields, but
the regex captures the second and fifth non-empty fields in a line. The
fifth entry, however corresponds with the 'user' field, which is not
normally numeric, unless either numerical group names are used, or
the internal numerical user ID can not be translated to a non-numeric
user ID because it references a user theat does not exist on the
system - it comes from another system via cp, rsync, tar,
etc... - without converting the group number.

On top of that, the function tries to pad fields to a size that they
already have. I suppose the `ls' has been modified in the past to
accommodate larger fields. Correcting ls-regexp to capture the correct
'size' field will only lead to extra processing without any results.  

This is not specific to the emacs release I am using. The problem is
probably there for a long time already.
