I didn't follow the discussion here, but there is one thing I noticed - the throw away of the suffix. In my Vertico and Corfu packages I have the following problematic behavior, which is also present in the default completion (I copied the comment verbatim from vertico.el): ;; XXX There is a small bug here, depending on interpretation. When ;; completing "~/emacs/master/li|/calc" where "|" is the cursor, ;; then the returned candidate only includes the prefix ;; "~/emacs/master/lisp/", but not the suffix "/calc". Default ;; completion has the same problem when selecting in the ;; *Completions* buffer. Is it non-intentional that the suffix is thrown away? I accidentally replicated this behavior in Vertico and Corfu, but wasn't sure if this is how it is actually meant to be. Daniel
