Thanks.  This patch ports Python's makesetup to be usable with zsh, and
results in a Makefile identical to one created with bash.  I have not
checked whether other shell scripts in the Python package need similar
treatment.  Please report this to the Python folks (best if you also
mention the CONFIG_SHELL workaround I wrote in the previous mail).

Cheers,
Ralf
