bug#23724: 25.0.94; ediff-patch-buffer doesn't handle -p3 `ediff-patch-options' option

[Live System User]

Hi,

        I cannot seem to pass a specific patch obtion to
        `ediff-patch-buffer'.

        I set `ediff-patch-options' to "-p3".

        I have a patch that when invoking `ediff-patch-buffer'
        via:

           Tools->Apply Patch->To a Buffer

        gets me the error message:

           patch: **** Only garbage was found in the patch input.


        However, when using the following from the command line:

           patch --verbose -p3 < /tmp/G1.patch

        it works, as expected.

        The patch is a unified diff, if it matters and I am using
        GNU patch 2.7.5.

        Thanks.
