You raise two separate issues, so let's split them into separate
subthreads.

What do you expect to see?  How should the two strings ("build .." and
"explicitly ...") be handled?

Minimal example:

% print -rl -- '#!/bin/sh' 'cat <<"EOF"' '  --enable-foo  enable foo' '  --disable-foo  disable foo' 'EOF' >configure
% chmod +x configure
% ./configure --<TAB>
--disable-foo  --enable-foo  -- enable foo                                    
--disable-foo  --enable-foo  -- disable foo                                   

I think that's the best we can do without writing new C code to suport
multiline descriptions.

Cheers,

Daniel
