What steps will reproduce the problem?

1. Generate any graph structure
2. Call the write function with a list as the parameter, using more than one value in the list. For example :
   graph.write_svg(somefile, prog=['twopi', 'overlap=scale'])

Expected : The graph is generated using the extra settings specified
Actual : The library raises an error saying that the command line was invalid (with the example above : "InvocationException: Program terminated with status: 2. stderr follows: Error: twopi: can't open overlap=scale")

Pydot-1.0.28-py2.7, on windows 7 x64

I think the bogus line is line 1985 :
cmdline = [self.progs[prog], '-T'+format, tmp_name] + args

The error is that the args list is appended at the end of the command list, while they should be placed between the -T and input elements (the rule being that the input files must be placed at the end of the command)
