using Astyle to format the C code

[ashitpro]

I am trying to use Astyle to format my C code.
C code is generated by python script.

I have return statements like this:

func()
{
return cond1 && cond2 && cond3 && cond4;
}

I would like Astyle to format this as:

func()
{
return 
       cond1 && 
       cond2 && 
       cond3 && 
       cond4;
}

I tried several switches in Astyle with no luck.
Any idea ?
