I would not press tab after the '(' and would indent the following lins with as many tabs as are before 'if' followed by 5 spaces. So replacing a space with . here and setting a > where a tab would be:

>   >   if ( condition
>   >   .....&& condition
>   >   .....&& condition
>   >   .....xxx
>   >   ) {
>   >   >   statements;
>   >   }

I'd do this just because one can never be sure about the tabsize someone else might use later.

OTOH: I tend to include jEdit buffer options that will others give at least a chance to set the tabs I used when creating my files.
