[PATCH v2] emacs: Improved compatibility for window-body-width in Emacs < 24

[Austin Clements]

Fix byte compiler warning "Warning: the function `window-body-width'
is not known to be defined." by moving our compatibility wrapper
before its use and simplify the definition to a defalias for the old
name of the function.
---

Tomi pointed out that window-body-width simply used to be called
window-width, so this simplifies the wrapper to a defalias.
