Fill-paragraph (M-Q) in a reStructuredText document that is formatted
using "Line Blocks"
<https://docutils.sourceforge.io/docs/ref/rst/restructuredtext.html#line-blocks>
such as:

   | In Xanadu did Kubla Khan
   | A stately pleasure-dome decree:
   | Where Alph, the sacred river, ran
   | Through caverns measureless to man
   | Down to a sunless sea.

results in this:

   | In Xanadu did Kubla Khan | A stately pleasure-dome decree: | Where
   Alph, the sacred river, ran | Through caverns measureless to man |
   Down to a sunless sea.

but in this case it should leave the line breaks intact.  The code
should probably treat the vertical bars something like list bullets,
since continuation lines are possible, e.g.

   | This is the all the first line
     of output even though it's two lines
     of input.
   | This is second line in the output.
   | And this is the third.

(I searched <https://debbugs.gnu.org/cgi/pkgreport.cgi?package=emacs>
for a similar report.  Apologies if I was not thorough enough.)

Richard is right: Filling should consider line blocks. OTOH line
blocks are really a rarely used feature I guess, so it doesn't hurt
much.

I'll look deeper into the code. But don't hold your breath ;-) .

[ With all those Stefans around I feel like nothing can stop us.  ]

I think we "just" need to:

- set `paragraph-start` to match a line with a leading `|`.
- set `adaptive-fill-regexp` to match this leading `|`.

If the `paragraph-start` setting makes paragraph navigation inconvenient
(too fine-grained), we could try and set
`fill-forward-paragraph-function` to a function which let-binds
`paragraph-start` around a call to `forward-paragraph`.

If that's bug#24081, then I don't see any rejection there, only a
request for clarification (which you gave).  Then the bug was for some
reason closed several months later, with no rationale.

We could reopen the bug, of course (assuming it still relevant to
current versions of Emacs 30 and 31).  But that bug is about
message-mode, not about rst-mode, so I'm not sure it is the same
problem.

that is the bug number.  i also received an email reply, which i see is
not in debbugs, claiming that it were not a bug and overtly refusing any
acceptance of ot work on a fix.  i don't know why that reply is elided.

Neither do I.  Did that email CC the bug number, or was it sent only
to you?  And who sent it, if I may ask?

Excuse me for not being familiar with the bug system, but is it possible 
to discuss that bug in that bug's thread, rather than having a 
discussion about bug management in this thread about RST verse handling?

Thanks.

That bug is archived, so we cannot discuss anything unless we
unarchive it.

But we can stop discussing that here, since it's a separate issue.
Thanks for pointing that out.

It's not (that bug was about a prefix shared by lines of a paragraph,
whereas this bug is about a prefix which starts a new paragraph).

Not in my test, no.  With a paragraph like:

    | bblblbl
    | asdfasdf
    | asdasdf

M-: (and (looking-at adaptive-fill-regexp) (match-string 0)) RET
returns a string that contains only the leading spaces.

`paragraph-start` doesn't match those lines either.
