Subject: 26.3; Doc of recentf, particularly `recentf-list'
Date: Tue, 15 Oct 2019 15:45:48 -0700 (PDT)

Many users use recentf.  Likewise, libraries.  Nowhere is it said what
order the files are listed in, i.e., the order of the elements of
`recentf-list'.  The answer is apparently that, by default at least, a
file is pushed to the front of the list when it is "opened" or written.

A more exact answer is that `recentf-list' is in reverse chronological
order of calls to `recentf-track-opened-file'.  And by default that
function is added to these hooks: `find-file-hook' and
`write-file-functions'.

I think that seems pretty self-evident -- the doc strings talk about
"most recent" etc, so what other ordering could be meant?

So I don't see anything to fix here and I'm closing this bug report.

It's not obvious at all.  That the 30 most recently
opened files are listed says _nothing_ about the
order in which they're listed.

And nothing is said about the situations when (by
default) the list (`recentf-list') is updated.
The answer is in the hooks.  It's not about
re-selecting the window of a file buffer or
changing a file outside Emacs, for instance.
(Not by default, at least.)

Unfortunate.

Thanks, I added that.
