Vertico completion options fringes are missing

[curable-online]

I have seen the news for the new release and read that it hides the fringes for line truncation.

I think they were useful, serving the purpose of hinting that the line doesn't at the right end of the window, and you can scroll to read the remaining of the annotation.

Can we have its removal, at least, as an option?

Of course, I may be able to change the behaviour to my need, if you think it's not a good idea.

I don't think the fringe indicators are useful in the context of Vertico. They add mainly noise for annotations which are only slightly too wide. Annotations are usually truncated to the correct window width, see for example Marginalia. I never scrolled the minibuffer window to see more of an annotation in years of usage. I also had the fringe indicators deactivated for a long time. Therefore I want to keep this for now as is, but I may reconsider if many users request an option. For now you can advise the vertico--setup function to change the setting or to kill the local variable.

Well, it is not only the annotation’s “docstring” that passes the
edge of the window (it’s usually NOT the doc-string part of the
annotation that overflows), but the filename that comes after it.
For example, when looking up for symbols using ‘C-h o’, the path of
the library that contains the symbol is also displayed after the
doc-string, which often passes the window boundary and
is truncated.

Also, please note, that it really depends on the size of one’s screen
and the size of the font. So, perhaps it never occurs to you, while
it always occurs to someone who has a small screen or big fonts.

Here's the advice I'm using to undo this change, in case it helps anyone:

(defun fixed-vertico--setup (vertico--setup &rest arguments)
    (let ((fringe fringe-indicator-alist))
        (prog1
            (apply vertico--setup arguments)
            (setq fringe-indicator-alist fringe))))
(advice-add 'vertico--setup :around 'fixed-vertico--setup)

The following simpler advice should do:

(advice-add #'vertico--setup :after (lambda (&rest _) (kill-local-variable 'fringe-indicator-alist)))

When I updated vertico (before openning an issue here), I wrote the
following which doesn't use advice stuff (I'm not good with advices).

(defun my/kill-local-fringe-indicator-alist ()
  (when vertico-mode
    (kill-local-variable 'fringe-indicator-alist)))

(add-hook 'minibuffer-setup-hook
          #'my/kill-local-fringe-indicator-alist)

I don’t know how much good is it.

FWIW I reverted the fringe-indicator-alist change in Vertico. Vertico leaves the variable untouched now.
