Relation to [1]?  It uses a different top-of-file directive, but
nevertheless seems to be possibly related.

[1] https://github.com/zpm-zsh/dropbox/blob/master/functions/_dropbox-cli
[2] https://github.com/ivoarch/dropbox-zsh-completion/blob/master/_dropbox

Suggest s/$line[1]/${line[1]}/ for forward compatibility with
a potential future «:$» history modifier.  (And -r to 'read')

Aside: I wonder why we don't use a «_call_completion_function()
{ readonly -i n=$compstate[nmatches]; "$@" && (( $compstate[nmatches] > $n)) }»
wrapper around calls to $_comps[foo]: that'd save every single
completion function having to manage $ret explicitly.)
