Then you're still doing it the hard way: all you need is to do
exec_set_found(found) immediately before anyplace that's going to
return.  You don't need to move the returns.

Perhaps the refactoring is worth doing anyway, if it improves the
readability of the code; but if it makes it worse then there's no need.
It's hard to tell about this just from looking at the diff --- what
do you feel about what you did?
