Description

When analysing the usage pattern of a recursive function we need to consider the way the result is used in
both non-recursive and recursive calls. This may require reanalysis of the body. To check whether reanalysis
is necessary we need a fully recursive comparison of the usage patterns. The previous code did not go deeply
enough. It turns out that 744d14 avoided the problem but did not properly solve it.
