bug#72523: 28.1; rst.el: indentation from TAB key in rst mode (ReST) is wrong when directive as an option

[jfbu]

Hi,

I could not find a bug tracker restricted to rst.el (reStructured Text mode). I was told rst.el is now maintained as part of Emacs, not at [Docutils](https://sourceforge.net/projects/docutils/).

Here is my report:

Consider editing in Emacs a file `test.rst` and having typed so far

~~~rest
.. note::
   :name: test
~~~

then insert a blank line and hit the TAB key on next one.  The cursor will align with `test`,  not with `:name:`.

This produces extra space in output when processed either by rst2html or integrated into a Sphinx projet.  For context see [this Sphinx comment](https://github.com/sphinx-doc/sphinx/issues/12742#issuecomment-2275622334).

I am using a file rst.el.gz integrated to my Emacs 28.1 which contains
~~~lisp
;; Maintained by the release process.
(defconst rst-official-version
  (rst-extract-version "%" "OfficialVersion: " "[0-9]+\\(?:\\.[0-9]+\\)+" " "
		       "%OfficialVersion: 1.5.2 %")
  "Official version of the package.")
(defconst rst-official-cvs-rev
  (rst-extract-version "[%$]" "Revision: " "[0-9]+\\(?:\\.[0-9]+\\)+" " "
		       "$Revision: 1.1058.2.9 $")
  "CVS revision of this file in the official version.")
~~~

I tried with electric-indent-mode both on and off.  No change.
Regards,
jfbu

This is not a bug, it's a feature.

You may hit TAB again to jump to the previous alignment point. You may
repeat this to cycle through all alignment points.

I did completely overlook that feature! Sorry about that...

~~~rest
.. note::
   :class: w
~~~ 

First TAB aligns with w, second one aligns with the "a"
of class and "e" of note and third one is the one a priori
most expected. Fourth one goes back to start of line.

If the alignment points were cycled in reverse order from now,
that would solve my use case ;-)

Best,

Jean-François

Thanks, so I'm now closing this bug.
