* lisp/dired.el(dired-get-marked-files): Added optional argument `marker-char'. If non-nil, the files retrieved are those marked with MARKER-CHAR. Otherwise the returned files are those marked with `dired-marker-char'. Callers are not affected: the arg is optional and added at the end of the parameter list.
