"*Function called to set up windows.
-Ediff provides a choice of two functions: ediff-setup-windows-plain, for
-doing everything in one frame, and ediff-setup-windows-multiframe,
+Ediff provides a choice of two functions: `ediff-setup-windows-plain', for
+doing everything in one frame, and `ediff-setup-windows-multiframe',
which sets the control panel in a separate frame. Also, if the latter
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
+ 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
