I have another problem with ffap: it can't find a file if file name
contains spaces.  I fixed this problem by the new function:

(defun my-find-file-at-point-or-region (&optional arg)
  "Find filename at point or selected by region.
This function is useful, when filename contains spaces, and so can't
be fully matched by `find-file-at-point'.  In this case user should
manually select region around the full filename and invoke this command.
This function also maps UNIX filenames to Window$ filenames."
  (interactive "P")
  (let ((filename
         (if (and transient-mark-mode mark-active)
             (buffer-substring-no-properties (mark) (point))
           (ffap-string-at-point))))
    (and (eq system-type 'windows-nt)
         filename
         (string-match "^/dos/\\([A-Za-z]\\)\\(.*\\)" filename)
         (setq filename (concat (match-string 1 filename) ":"
                                (match-string 2 filename))))
    (or (and filename (file-exists-p filename))
        (setq filename (ffap-guesser)))
    (find-file-at-point (ffap-prompter filename))))

But I think it is not the right thing yet.  Ffap should be fixed
to pick up full file name with spaces without requiring the user
to select a region.
