Yes, I spent 10 minutes trying to decide if I should send this patch
at all ... (ie how much public humiliation could I take :-D )

I really don't know. I'm not sure I will ever know. A couple of years
ago, when I was trying to debug the (harmless) "--color" spew, I found
(via google, etc) numerous accounts of similar problems, with various
workarounds for specific problems. One such account claimed that the
cause of the problem was an official "fix" from Microsoft (as part of
a service pack) which worked just fine on Windows Vista (and later) but
had this known side-effect on XP. Since it fixed the problem it was
intended to fix, even on XP, and the unfortunate "side-effect" on XP
should be quite rare, they decided to apply it on XP anyway. :(

Hmm, on reflection, it would probably be best if you just drop this patch.
I can keep it locally and apply it on top of any branch I want to test.
(Actually, it would be easier to simply revert commit 7bc0911d.)

Sorry for wasting your time.
