I believe I've got it now. With a trick from the FAQ.
if hasattr(self, scommand):
parameter_s = " %s " % parameter_s # Protect quotes at the end
return shell+scommand+'(parameter_s=r"""%s"""[1:-1])' % parameter_s
else:
return shell+line+'()'
You put extra spaces on, then pull them off with the slice after
quoting is complete.
