Re: vertical fido-mode

Hi! I'm the author of icomplete-vertical. I'd be very happy to see the icomplete-vertical functionality included in Emacs, and Ergus is completely correct:

> But as I see the code in icomplete-vertical-mode; it relies in a hook (icomplete-vertical-minibuffer-setup) and an advice (icomplete-vertical-format-completions) which in principle we don't need with a very simple modification of icomplete-completions and icomplete-minibuffer-setup. If icomplete-completions produces the formated output it will be more efficient and clean than adding an advice or do a reformat.

That's exactly what should be done: not include the icomplete-vertical package as is, but instead make small modifications of the existing icomplete package to incorporate the changes.

> There are also some customizable options that for a simple working vertical mode we shouldn't need (like icomplete-vertical-separator-alist or a face icomplete-vertical-separator) unless we want to add them now.

Again, Ergus is completely right! Those, with the benefit of hindsight, are over-engineered and shouldn't be included in Emacs. Heck, they shouldn't even be in icomplete-vertical. (I've learned that lesson and although I subsequently wrote a few more completion UIs, I didn't include options analogous to those.)
