need to explicitly create newline on command prompt

need to explicitly create newline on command prompt

[Eric Smith]

<cut and paste from terminal>
[eric@plum ~]$ perl -e 'print "abc "'
[eric@plum ~]$ echo abc 
abc 
[eric@plum ~]$ perl -e 'print "abc \n"'

"'abc
[eric@plum ~]$ zsh                  
[eric@plum ~]$ perl -e 'print "abc "'
[eric@plum ~]$ perl -e 'print "abc \n"'
abc 

[eric@plum ~]$ bash
bash-2.03$ perl -e 'print "abc "'
abc bash-2.03$ perl -e 'print "abc \n"'
abc 

</cut and paste from terminal>

With zsh, I have never been able to get output of a perl command
unless an explicit "\n" is entered.  A straight echo or even:
echo 324542| sed 's/3/9/g'
does print out. (Also there is that weird `"'abc' output.

With bash all is as it should be.

Any ideas where I could look t fix this?

How do you get _this_?
Can't reproduce such behaviour.

Yes. This happens because zsh clears the whole line before drawing a
prompt. You can workaround the problem:
precmd() {
   echo
}

Bash doesn't clear the line before drawing a prompt, so this behaviour
happens...

The perl command issues some output, but the output will be overwritten
by zsh's prompt.
