Thanks for your response.  Yes, it is the case, I have "already seen"
parents, but I have `(display . all)' in my `gnus-parameters', so Gnus
shows the old messages.

I tried your suggestion, but no avail.  With or without your suggestion,
I have threads in the same group where Gcc works and looks like this:

O  +  80: → emacs-devel@gnu.or 19-Aug Emacs binaries for Windows
OA ├─▶   58: Name 1               19-Aug 
O  │ └─▶  139: → Name 1             19-Aug 
OA └─▶   85: Name 2               19-Aug 
O   └─▶   63: → Name 2             19-Aug

In other, newer threads, my messages (→ Name 1) don't show up, only when
I hit `A r'.

I get something by setting `(gnus-build-sparse-threads 'more)' in
`gnus-parameters', but it has other side effects:

O  +  24: Name 1               09-Sep Re: Real key-val query for \includegraphics

OA  └─▶   17: Name 1               10-Sep 

My message show up, but looks totally broken (0:     ).

I was referring to Gnus manual, section 3.1.1 Summary Buffer Lines:

‘k’
    Pretty-printed version of the number of characters in the article;
    for example, ‘1.2k’ or ‘0.4M’.

In my `gnus-parameters', I had this for this group

(gnus-summary-line-format "%U%R%z%B%(%4k: %-20,20f%) %d %3{%s%}\n")

But it doesn't work and our thread looks like this (after `A r'):

✓  + n/a: → help-gnu-emacs@gnu 02-Sep Gnus: Gcc and imap folders
✓  └─▶ 5.0k: Tassilo Horn         12-Sep

I'm running out of ideas how to get my hands on this.

Best, Arash
