1. Truncating labels is done ATM with

       (truncate-string-to-width label width nil nil t)

   It would be nice if there was an option to choose the `ellipsis'
   argument.  (The code already deals with unicode, so IMO it makes
   sense to use "…" with an alternative of "-" in
   `tabulated-list-glyphless-char-display'.)

2. When I use `electric-buffer-list', if I happen to click on a column
   header it sorts the buffer according to that header, and it even
   makes that choice persistent.  That's nice, I guess, but there
   should be some way to go back to the default original order -- and
   maybe I'm missing something obvious, but I don't see any good way
   to do that.  (If I hit it by mistake, the only way I found to go
   back to the default is to quit the electric buffer, then use
   `list-buffers' to get it in plain mode, then kill it so that it
   gets recreated next time.)

(setq truncate-string-ellipsis "…")

Oh, good...  Any estimates for the release of v25?

And I'm assuming that there's some way to change the subject of this bug
to reflect the second point -- or is it better to re-submit?


And semi-related, ebuff is full of problems around not turning itself
off when you switch outside -- enough that it makes me suspect that the
code is either not actively maintained or very active so things changed.
If this is incorrect, should I submit another bug?

Some time before 2025.

Not actively maintained is much closer to reality, IIUC,

Indeed.  So the default is to sort by whatever order `buffer-list'
happens to return them in.  Which can of course be useful.  But there is
no easy way to return to this sort order.

I'm not sure how easy this is to fix, but:

What is the expected behavior here?  Does it make sense to make `C-u S'
go back to the default sort order?  Or should perhaps a right click at
the relevant column header reset it?

(Note that `electric-buffer-list' is the same as `list-buffers' for our
purposes here.)

(TBH, I don't even remember the context -- I was maybe looking for a
replacement for `bs.el`.)

FWIW, I'd expect a click to go from nothing to ascending to descending
back to nothing.

(Just tried `electric-buffer-list` again, it is broken in an amusing
way for me, where a click leads to some infinite loop that keeps the
window top following the mouse...)

Right.  But this would only be useful in certain buffers, so I'd suggest
this behavior to be optional.

The attached patch should do it.  Comments welcome.

(And as I'm about to send this, I realize that we would probably want
the same behavior also for the `tabulated-list-sort' command?  Either
for consecutive invocations or for the prefix argument.)

Sounds like you have stumbled into a bug that should be reported?

This was fixed in Emacs 28 -- `C-u - S' reverts back to the original
sort.

I've now added the `S' command to `electric-buffer-list', too.

I'm not sure this would be used much -- does other things that sort
based on clicking the headers work this way?  But I don't oppose adding
it if it's something that'd be used.

Any opinions?

Nobody had an opinion here, and I my feeling is that this is something
that wouldn't be used a lot, so I'm closing this bug report.
