You mean keep it as it was up to r1.35 ("--skip-stderr") or between
r1.36 and r1.41 ("--skip-stdout")?

Well, the problem I tried to fix was that we *did* break backwards
compatibility with releases <= 1.4.2 and users complained about that.
My idea was to make things somewhat compatible with both the old and the
new behaviour.  However, I agree that the result really seems too
clumsy, especially as it doesn't provide real backwards compatibility
anyway.  Actually, I thought about reverting that in favour of the
options you suggested myself.  Convinced, will do.
