1. At its end, we have
```
function ys=NondistortionarySteadyState(M_)
if exist([M_.fname,'_steadystate.m'],'file')
eval(['ys=',M_.fname,'_steadystate.m;'])
else
ys=zeros(M_.endo_nbr,1);
end
```
which seems to miss the case of a `steady_state_model`-block. It's also not clear why we have this in any case. At the end of the function, we write `ys` based on this input. But throughout the function, like in
```
[U,Uy,W] = feval([M_.fname,'.objective.static'],zeros(endo_nbr,1),[], M_.params);
```
we assume the steady state to be 0.
2. The handling of error codes should be nested into the `print_info`-framework as opposed to always issuing errors.
3. The function is very verbatim in terms of providing diagnostics. That is useful in standalone code, but a bottleneck when run in a loop like `estimation` where we only want to discard infeasible draws without providing diagnostics.
4. The order of some checks is strange. We do computations on the model before checking e.g. whether the number of instruments is valid. We should be able to do this without computing the Jacobian. Also a check like this should only be done once in the context of estimation and does not belong into the core engine. This suggests a different factorization.

This is a regression from 4.5.
Unfortunately, the test at the end of `Gali_discretion.mod` did not catch the problem, because of the specific evaluation rules for `NaN`.

```
>> dynare example1 '-DA="nthn thnth"' -DB=[1,2, .3] -DB=( oe )
-DA="nthn thnth"

The output above comes from simply printing the arguments of `varargin`.
We should be able to thus simply add single quotes around every user-provided argument in `dynare.m` and pass these directly to the preprocessor for processing. We'd then require that all strings be double-quoted and could potentially even handle macro expressions (not just base values) in `-D` arguments.Matlab is actually quite good about keeping user-provided arguments together.
