[PATCH] git-gui: Fix pre-commit hooks under MinGW/MSYS

["Alexander N. Gavrilov" <angavrilov@gmail.com>]

From: Alexander Gavrilov <angavrilov@gmail.com>

Apply the work-around for checking the executable
permission of hook files not only on Cygwin, but on
Windows in general.

	This is a fix for msysgit issue #118.
	(http://code.google.com/p/msysgit/issues/detail?id=118)

	It may be possible to fix this in a better way, e.g. perhaps assume
	that if the hook exists on Windows, then it's executable (msysgit
	uses renaming to disable hooks), or at least check existance
	before running the shell, but I don't know enough Tcl to do it.
