You could use _call_program but given that the default in this case
involves two separate invocations of sed and a loop, allowing the
function to be overridden is probably easier for users. I'm not overly
fond of shielding functions that way so tend to only do it for functions
that someone is likely to want to replace. But no objection from me in
this instance. Note that it is more efficient to use (( $+functions[...
and not $#functions[..

It definitely would be best renamed with _ant_ as a prefix. I would just
call it _ant_targets and include the compadd line in the function.
Perhaps whoever wrote it wanted to use it outside of completion. It
could also be rewritten to use fewer subshells.

I had to consult the git history myself to get the answer to that. And
while I did originally write it, there has been considerable change
since. The original had no separate function for targets. And it's a
long time since I used ant so it's not a completer I've ever had much
reason to look back at. I agree with everything you've said in the
feedback for this patch and haven't replied before because I didn't have
anything useful to add.
