Two Assertion failures on Windows tests (script_header)

I do regularly run the tests on Windows. Back around 0.6.21 or so, the tests were passing on Windows in totality. When I run the tests now, I get two failures in tests due to shebang lines in scripts (complete transcript):

======================================================================

      )

I've been ignoring these test failures because I believe it is the tests that are broken and not the implementation. I suspect these tests will not fail when there is not a space in the path to python.exe.

Shebangs do not work at all on Windows, so these tests could be skipped on Windows.

Quotes in shebang are interpreted as integral part of path (at least on Linux):

$ cat test1.sh
#!/bin/bash
$ cat test2.sh
#!"/bin/bash"
$ ./test1.sh
$ ./test2.sh
bash: ./test2.sh: "/bin/bash": bad interpreter: No such file or directory
$

Such quotes should not be added around a path with spaces. Probably tests should be skipped in such situation.

I believe that both setuptools and the Windows py launcher both honor the shebang in Python scripts and more importantly do a better job of it than Unix does, supporting valid filenames with spaces in them. Furthermore, I'd like to get these tests passing as they're not only testing the headers.

Fixed script header generation in easy_install tests. Fixes #37.
