Eli, as you know, 
I am not a C specialist at all...

But I didn't invent that rule either.
This rule part of gdb_ari.sh since it's introduction in CVS ss repository
back in 2002.

 It's probably now your chance to challenge this rule...
I would tend to agree that an assignment should be a statement on it's 
own, but you could rightly consider this as a 'pascal' language
preference!
