tests/warnings/*.m:
Bring the programming style of these modules up to date,
except where the problem being tested for seems to be related
to the old programming style
In the infinite_recursion test case, add code that we *should*
warn about, but currently don't.
tests/warnings/*.m:
Update the expected outputs to account for the changes in line
numbers, and the fact that the compiler computes the contexts
of (if C then T else E) if-then-elses differently from (C -> T; E)
if-then-else (it takes the context of the "then" vs the context
of the ";").
Delete arg_order_rearrangment.exp2. It was long unused, but
deleting it in CVS would not have allowed us to put it back later.
