Thanks for the input.

 * ../../python.exe changed to sys.executable.
 * Figleaf is 69kb.  It seems to work fine doing it all in one read()
call.  Should it be chunked?
 * Optparse isn't used, partially because I'm lazy and partly because
I'm not actually parsing the command line, just chopping the first
element off and then passing it off to regrtest.py.  It is the job of
regrtest.py to parse the command line. <-- My opinion
 * traceless.  I think I should remove the file.  Having tests that fail
don't hurt figleaf, as far as I know, so there isn't much point to
avoiding failing tests.

Uploading a new version of the .zip file that uses sys.executable and
does not use traceless.

I don't know if figleaf works on windows and I don't have a system to
test with.
