bug#14013: 24.3.50; dired-isearch-filenames-regexp is matching text outside filenames

.* matches a whole line.  We can't hide from Isearch the fact
that lines in Dired contain more details besides filenames.
However, you can hide these details and leave only filenames
by using `dired-hide-details-mode' or typing `('.  Then .*
will match only visible filenames.
