I've just commited this fix:

    commit ab23fa4eb22f6557414724769958a63f1c59b49a (HEAD -> master, origin/master, origin/HEAD)
    Author: João Távora <joaotavora <at> gmail.com>

        Sort by recency in flex completion style when no flexy stuff happening

There is still the C-x f bug, but that wasn't in your report.  You seem
to be concerned with M-x and C-x p f (as am I, by the way)

That other problem isn't even very well understood by me.  C-x f looks
for files in a single directory, but minibuffer history has whole
paths...  I think it deserves a new bug report if anyone really cares.

For now I think particular bug report can be closed.  If anyone
disagrees, let me know.

Subject: 28.0.50; fido-mode not sorting by recency

In 'emacs -Q', this is what I did:

- M-x savehist-mode RET
- M-x fido-mode RET
- M-x icomplete-vertical-mode RET
- M-x emacs-init-time
- C-x p p, pick a Git-versioned directory RET
- f, pick the fourth candidate, C-x k RET
- M-x now shows pr-ps-file-preview on top
- C-x p p, pick the only available project
- C-x p f does not offer the previously selected candidate

Is it possible to make fido-mode sort the candidates by recency?
