Routine Description:
sets the window text of hWnd to be the "scrunched" version of
the path string in szInPath. If the path string is too long
to fit in a single line of hWnd, then directories are removed
from the path until it does fit. The directories are removed
from the "top" down. The root drive\dir is kept as is the
filename and as many directories that will fit.

IN HWND hWnd
handle of window to put text in

path to display in window
