Patch: prefer-window-split-horizontally

[Tassilo Horn]

Hi all,

I reworked Fredrik Axelsson's patch [1] since I couldn't contact him for
more than a month.  I think now would be a good time to include it.

It adds this new variable:

,----[ C-h v prefer-window-split-horizontally RET ]
| prefer-window-split-horizontally is a variable defined in `C source code'.
| Its value is t
| 
| 
| Documentation:
| *Non-nil means that windows are split horizontally, i.e. side-by-side, instead
| of vertically by `display-buffer'.
| An integer value means that windows may only be split horizontally if the 
newly
| created window is at least as wide as that value.
| 
| You can customize this variable.
| 
| [back]
`----

It works nicely here, but since I'm no appreciator of emacs internals
please have a close look at it.

Bye,
Tassilo
