BUG: zsh overwrites last line of output

[Peter Makholm <peter@xxxxxxxxxxx>]

Try look at the following:

galar% echo $ZSH_VERSION 
3.1.9
galar% echo -n foo
galar% echo -n "foo\nbar"
foo
galar% 

Somehow zsh overwrites the last line of output if it doesn't end with
an new-line. On a (very) slow terminal I've been able to see that the
"bar" in the last example actually gets written.
