ediff-diff-options is ignored

[Jesper Harder]

Hi,

Ediff ignores the `ediff-diff-options' option.  The background is that
I need to compare utf-16 files, which diff consider binary unless you
pass a "--text" option.

Steps to reproduce:

* Customize `ediff-diff-options' to "--text"
* Create two text files, save as utf-16
* `M-x ediff-files' on the two files.
* Result: The *ediff-errors* buffer contains this message: 

   Binary files /Users/harder/a.txt and /Users/harder/b.txt differ

  which means that the "--text" option wasn't passed to diff.

It works correctly in Emacs 21.4; and the regression appears to have
been introduced by this change:

        * ediff-diff.el (ediff-ignore-case, ediff-ignore-case-option)
        (ediff-ignore-case-option3, ediff-actual-diff-options)
        (ediff-actual-diff3-options): New variables to control case sensitivity.
        (ediff-make-diff2-buffer, ediff-setup-fine-diff-regions)
        (ediff-setup-diff-regions3): Make aware of case-sensitivity.
        (ediff-toggle-ignore-case): New function.
        (ediff-extract-diffs, ediff-extract-diffs3): Preserve point in buffers.
