Terminal thinks start of line is first character of previous line

[Eitan Adler]

For some reason the output of my terminal at times seems to put the
first character of a line as the last character of the previous line.
This occurs with x11/Terminal x11/Eterm x11/xterm and probably others.
As far as I could tell this does not not occur on console but I have
not tested as thoroughly.

echo $TERM $COLUMNS
xterm 140

I'm unsure what other debugging data is needed. I am able to provide
any other data that might be needed to solve the problem though.
