Of course... My own stupidity.

It did raise the question for me, what would be the recommended way to
'group' expressions, where other languages would use brackets, like:

if (((q==1)) || [[ $r ]]) && grep -q $s $file
  echo "$s is in $file, and either q is 1 or r is not empty"

I guess this works, but it spawns a subshell. Is there a better way?
