  * Fix a bug in translating (n+k) patterns to code.
  
    The symptom was that
        foo (n+1) Foo = 1
        foo (n+1) Bar = 2
        foo _ _ = 3
        main = print (foo 1 Bar)
    was offering 3 as result, not 2 as expected.
  
    The cause was that the two equations were being matched in an
    nested if..then..else sequence, with (n>=1) as the condition.
    The correct way is to sequence the matches with FATBAR, so the
    second match is actually attempted.
