Scrolling the article at point in gnus-summary-mode

Scrolling the article at point in gnus-summary-mode

[Bastien]

Hi,

when hitting RET or SPC to scroll an article from the summary buffer,
Gnus scrolls the article in *article*.  

But if the article in *article* is _not_ the article the point is on in
the summary buffer, then RET will scroll the wrong article.  RET should
make sure that the article at point in the summary buffer and article in
*article* are the same before scrolling.

Did someone else already encounter this issue?

I think I've seen this.  I have definitely observed the following, which
I suppose is related: When more than one Gnus Summary buffer is open,
typing h in the Article buffer goes to that last selected Summary
buffer, even if the article comes from another Summary buffer.  I
suppose this has to do with Gnus only having one *Article* buffer, while
allowing multiple Summary buffers, which are differently named.  I used
rename-uniquely on the *Article* buffer but that didn't make h work
better.

Me, too.

You can have one article buffer per summary buffer.

,----[ C-h v gnus-single-article-buffer RET ]
| gnus-single-article-buffer is a variable defined in `gnus-sum.el'.
| Its value is t
| 
| Documentation:
| *If non-nil, display all articles in the same buffer.
| If nil, each group will get its own article buffer.
| 
| You can customize this variable.
`----

Or to have several article buffers in the same summary buffer, have a
look at:

,----[ (info "(gnus)Sticky Articles") ]
| When you select an article the current article buffer will be reused
| according to the value of the variable `gnus-single-article-buffer'.
| If its value is non-`nil' (the default) all articles reuse the same
| article buffer.  Else each group has its own article buffer.
| 
|    This implies that it's not possible to have more than one article
| buffer in a group at a time.  But sometimes you might want to display
| all the latest emails from your mother, your father, your aunt, your
| uncle and your 17 cousins to coordinate the next christmas party.
| 
|    That's where sticky articles come in handy.  A sticky article buffer
| basically is a normal article buffer, but it won't be reused when you
| select another article.

Nevertheless, your and Bastien's problems look like a bug.

Thanks for the tip/reminder (I didn't know about the first and forgot
about the second)!

Nevertheless, it's always a pleasure to unbury some still-unread part of
Gnus manual!
