python executable path "python" is correct provided that you
have python on your search path.  it is the best guess for
"one size fits all" installer.  you may build your own
installer by running 'python setup.py bdist_wininst' on your
windows system - it will have the paths adjusted for your
system.

i am not aware of any way to alter the scripts by python
installer stub.  are you?

yes, batch files have unix format newlines because they are
built on unix-like system.  what's the problem?  they run
perfectly well on windows, at least on windows nt line.
