M-x compile and window splitting

[Frank Schmitt <ich@frank-schmitt.net>]

Hello,

In Emacs 22, when your frame is say 1400x1000 and displays just one
file, M-x compile splits the window horizontally and uses the variable
compilation-window-height to decided on the height of the window showing
*compilation*.

In Emacs 23, the window is split vertically instead of horizontally and
compilation-window-height doesn't seem to have any effect anymore.

I like the change that the window is split vertically instead of
horizontally, however I see some issues:

- compilation-window-height looses its meaning (the variable is not
  mentioned in info but shows up in M-x customize-group <RET> compilation)
- the change doesn't seem to be mentioned in NEWS (at least I couldn't
  find it)
- there doesn't seem to exist a possibility to influence the width of
  the new window
