Re: 4855 does not work in all cases

:To test - just try something like
:echo "----(80 characters)\n===" and see if you get extra newline. I believe,
:this is exactly what happens with AIX term. It does not happen with all
:terminals program I'm using here (xterm/dtterm) :-)

For am (automargin) terminals: 
  a non-special character must be output at terminal width. 
For non-am terminals:
  a return sequence must be output at terminal width.
 
In each case, any cursor movement must be done after that as its behaviour
cannot be reliably determined (due to certain unmentioned terminal emulators
and not due to dumbterms which tend to have pretty standard behaviour).
I'm pretty sure zle_refresh.c violates this in some special cases (prompt
things I think) so I guess I better fix those soonish.  Printing outside of
zle_refresh.c I've got no idea about.  Sometimes I get the urge to look at
combining all the normal output, e.g. lists, into a more generic
zle_refresh.c  but don't worry, I've kept those urges in check.
