Sorry about the duplication to zsh-workers recipients ... I meant to change
the destination address but then clicked Send too quickly.

On further reading of the compadd doc, `compadd -ld ...' appears to be
the thing to do, though it's a bit convoluted.
autoload -U compinit
compinit
function _aecd {
local change_descriptions reply
# Force change_descriptions to be a one-element array
change_descriptions=("$(aereport changes -unf | grep -v completed)")
# The name "reply" is not special here, I just happened to use it
reply=($(aereport changes -terse | grep -v completed | sed -e 's/ .*$//'))
# Display the change_descriptions in place of the first completion
compadd -ld change_descriptions $reply[1]
# Add the rest of the completions, but don't display them in the list
compadd -na 'reply[2,-1]'
# Force the list to appear so the descriptions are visible
compstate[list]='list force'
}
compdef _aecd aecd
It does appear that "compadd -d" still produces a sub-optimal display in
this case if there are any lines in $change_descriptions that have exactly
$COLUMNS characters; but it properly returns the cursor to the right spot
even so.
I don't know what the output of `aereport changes` looks like, so it may
be that there's a simpler solution. For example, if the same number of
lines will be returned by `aereport changes -unf` and `... -terse`, this
will work:
function _aecd {
local change_descriptions reply
change_descriptions=(${(f)"$(aereport changes -unf | grep -v completed)"})
reply=($(aereport changes -terse | grep -v completed | sed -e 's/ .*$//'))
compadd -ld change_descriptions -a reply
compstate[list]='list force'
}
You may also wish to drop that compstate[list] assignment and instead use
the force-list style to control it:
zstyle ':completion:*:aecd' force-list always
See the manual for more.
