I think part of the issue is that some of the output is to stderr.
stderr and stdout can overwrite each other in fascinating ways.

I'd urge you to use "scp -v foo bar 2>&1" to keep all of stderr and
stdout, and avoid overwriting one with the other.

Have you considered using "rsync -e ssh" instead of scp, to get more
meaningful dialogue for most transfers?
