When the variable `dired-isearch-filenames' is non-nil then it is not
possible to search the entire buffer because both `C-s' and `M-s f C-s'
start filename isearch.

The following patch changes `M-s f C-s' to start a non-default isearch,
i.e. isearch opposite (filenames vs entire buffer) to the value of
`dired-isearch-filenames' (that affects isearch started via `C-s'):
