[TxMt] Nonstandard C indentation rules

[Alexey Sudachen]

Hello,

I need to change indentation rules to correctly indenting C code like this

int func(int a)
 {
   if ( a )
     {
       return do_it();
     }
   else
     return 0;
 }

here is two spaces before '{' and two after.

How I can do it? The regxps in indentation preferences are quite hard to understand right.

Muchas gracias,
Alexey.
