compctl -y problem.

compctl -y problem.

[Cesar Crusius]

Hi. I am having a problem with the "-y" option for compctl. Namely, I
have

compctl -K project_changes -y '$change_descriptions' aecd

where 

function project_changes {
  change_descriptions=`aereport changes -unf | grep -v "completed"`;
  reply=(`aereport changes -terse | grep -v "completed" | sed -e 's/ .*$//'`);
}


What happens now is this: $change_descriptions turns out to be a table
with many lines. When I press <Tab> after aecd, the table shows as
expected, but the cursor does not return to where it should. It goes
to one line below where I originally typed <Tab>.

Any clues?

Which version number of zsh are you using?

Do any of the lines in the output, particlarly the last line, contain
exactly the same number of characters as the width of the terminal?

This one works perfectly.

Thanks!

zsh --version gives

3.1.9-dev-6

It also happends independently of the terminal (console, rxvt, xterm),
so the problem's not there too.

No... Here's a quick test that also fails:

function tests {
  test_desc="asdasd
asdasdas
asdasd"
  reply=(`ls`);
}
compctl -K tests -y '$test_desc' testa

When I try to complete 'testa' I get the same behavior.
