Rework test_script a little bit.


Don't allow someone to request a stdin request to echo.
Echo never reads from stdin, it just echos its arguments.
You use 'cat' if you want to read from stdin.

A few other fixes because the tests were using filenames
that are actually illegal on Windows, rather than just
nonexistant.


Change the exception handling for commands so that
unknown errors don't get silently squashed and then
turn into hard-to-debug errors later.

test_script now passes on Windows.
