Sorry for resending, but the previous version got dropped from the
main git mailing list due to a HTML-subpart. Converted to plain-text.

OK, I can reproduce it in Git Bash now, and by doing "git push 2>&1 | od -c"
I can see that I'm getting "Message\033[K\n".

This looks a little bit puzzling, but the sequence matches ANSI_SUFFIX in
sideband.c. So it seems this is intentional. This dates back to ebe8fa73.

I wonder, shouldn't we check isatty also before assuming ANSI-sequences?
