Older versions of colorama break stdout/err when recursive functions

are compiled.

This test should work irrespective of colorama version, or indeed its

presence. If the version is too low, it should be disabled and the test
|

|
|
should work anyway, if it is a sufficiently high version or it is not

|
|
present, it should work anyway.
