Lessee, I can occasionally channel Guido, maybe I can channel Uncle
Timmy:
First of all, you have to remember that Uncle Timmy is an Evil Windows
abuser. Things that seem perfectly sane and normal to the rest of us
look like chaos and cruft to him (and vice-versa, of course).
The problem with stderr is that unless you understand it (which is
pretty straightforward to anyone who has drunk the Unix Kool-Aid), you
can get all kinds of unexpected output results, especially under
redirection. Without redirection, there's no way to differentiate the
combined stdout/stderr stream; contrariwise, if you redirect just stdout
with the intention of recording your test run, you'll be missing the
stderr stream in your log.
