(ediff-select-lowest-window): Use when rather than if. (ediff-setup-control-frame): Remove ediff-cond-compile-for-xemacs-or-emacs, since it is already inside a (featurep 'xemacs) test.

"*Function called to set up windows.
|
|
Ediff provides a choice of three functions: `ediff-setup-windows-plain', for
|
|
doing everything in one frame, `ediff-setup-windows-multiframe', which sets
|
|
the control panel in a separate frame, and
|
|
`ediff-setup-windows-automatic' (the default), which chooses an appropriate
|
|
behavior based on the current window system. If the multiframe function
|
|
detects that one of the buffers A/B is seen in some other frame, it will try
|
|
to keep that buffer in that frame.
|
|
|
|
If you don't like the two functions provided---write your own one.
|
|
The basic guidelines:
|
|
1. It should leave the control buffer current and the control window
|
|
selected.
|
|
2. It should set `ediff-window-A', `ediff-window-B', `ediff-window-C',
|
|
and `ediff-control-window' to contain window objects that display
|
|
the corresponding buffers.
|
|
3. It should accept the following arguments:
|
|
buffer-A, buffer-B, buffer-C, control-buffer
|
|
Buffer C may not be used in jobs that compare only two buffers.
|
|
If you plan to do something fancy, take a close look at how the two
|
|
provided functions are written."
