(dired-isearch-filenames): Add new context-dependent

option `dwim'.  Change non-dwim option from `dired-filename' to `t'.
Doc fix.
(dired-isearch-filenames-setup): Run filename Isearch only when
dired-isearch-filenames is t or dired-isearch-filenames is `dwim'
and the text property `dired-filename' at point is non-nil.
In this case also set isearch-message-prefix-add to "filename ".
(dired-isearch-filenames-end): Set isearch-message-prefix-add to nil.
(dired-isearch-filenames, dired-isearch-filenames-regexp):
Don't let-bind isearch-message-prefix-add since this is done now
in dired-isearch-filenames-setup.
