Incorrect function pointer arguments within argument

[dmlary]

Given the following code:

int cvStartLoop(int (*pt2Func)(int argc, char *argv[]), int argc, char* argv[]);

ffi-swig-generator outputs the following, invalid, ruby code:

attach_function :cvStartLoop, :cvStartLoop, [ callback([ :int, a().p.char ], :int), :int, :pointer ], :pointer

Note the a().p.char as the second argument within the callback.

ffi-swig-generator should output:

attach_function :cvStartLoop, :cvStartLoop, [ callback([:int, :pointer], :int), :int, :pointer ], :pointer
