[bug] completion makes input jump up one line

[bug] completion makes input jump up one line

[Mikael Magnusson]

under 4.1, if i tabcomplete, and one of the matches in the list is a 
multiple of $COLUMNS, ie, if the last letter of the match is in the 
rightmost column, the whole thing jumps up one line. i confirmed it with 
caphuso on #zsh, it happens in 4.1, but not 4.0
here is a "screenshot":

: caphuso on #zsh, it happens in 4.1, but not 4.0

I can reproduce this with:
 % zsh -f
 % setopt alwayslastprompt

I'm guessing the calculation in calclist() needs correction.

Does this look right?

Oops, that's what I get for starting to reply to email before all of it
has downloaded.

Your patch _looks_ right ... but wasn't something like this fixed at
least once before?  Do we have any idea how it got broken again?

Hmm, I don't remember any similar problem nor can I find a description
of one.  Anyone else have an idea about this?

Unless there are objections (or more clarification), I'll commit the patch
in workers/19474 before zsh-4.2.0

No, I was pretty sure there was a previous bug that occurred only when a
line displayed by zsh was exactly the width of the terminal.  It may have
been in a different part of the code, but I thought it was in completion
listings.  Maybe I'm hallucinating; I don't know what keywords to try to
search for it.  I may be thinking of the threads around zsh-workers/7053
and zsh-workers/7030.

Do you mean this one? http://www.zsh.org/mla/workers//2003/msg00344.html It
was different at first glance.
