It's difficult to reproduce this from some ASCII art.  I tried, and
couldn't really figure out what you were getting at.

Could you write a small shell script that demonstrates what you're
trying to show, and indicate where to look for the unexpected output?
If there's something actually going wrong, that will make a good basis
for a regression test.
