Add closed issues and PRs to 3.8 changelog

I used below script to list all GitHub issues and PRs that are not yet
mentioned in the changelog. It's almost empty now.

While at it, curate the "notable" section and move some entries around,
notably from "interactive improvements"  to "bindings".

```shell
ms="fish next-3.x"
{
    gh issue list --state closed --milestone "$ms" -L 500
    gh pr list --state all --search "milestone:\"$ms\"" -L 500

    set -- $line
    grep -qE '\W'$1 CHANGELOG.rst ||

 Notable improvements and fixes
 ------------------------------
-- ``functions --handlers-type caller-exit`` once again lists functions defined as ``function --on-job-exit caller``, rather than them being listed by ``functions --handlers-type process-exit``.
+- New function ``fish_should_add_to_history`` can be overridden to decide whether a command should be added to the history (:issue:`10302`).
+- :kbd:`Control-C` during command input no longer prints ``^C`` and a new prompt but merely clears the command line. This restores the behavior from version 2.2. To revert to the old behavior use ``bind \cc __fish_cancel_commandline`` (:issue:`10213`).
+- The :kbd:`Control-R` history search now uses glob syntax (:issue:`10131`).
 
 Deprecations and removed features
 ---------------------------------
 
 - ``commandline --tokenize`` (short option ``-o``) has been deprecated in favor of ``commandline --tokens-expanded`` (short option ``-x``) which expands variables and other shell expressions, removing the need to use "eval" in custom completions (:issue:`10212`).
+- A new feature flag, ``remove-percent-self`` (see ``status features``) disables PID expansion of ``%self`` which has been supplanted by ``$fish_pid`` (:issue:`10262`).
 
 Scripting improvements
 ----------------------
-- ``functions`` and ``type`` now show where a function was copied and where it originally was instead of saying ``Defined interactively``.
+- ``functions`` and ``type`` now show where a function was copied and where it originally was instead of saying ``Defined interactively`` (:issue:`6575`).
 - Stack trace now shows line numbers for copied functions.
+- ``foo & && bar`` is now a syntax error, like in other shells (:issue:`9911`).
+- ``if -e foo; end`` now prints a more accurate error (:issue:`10000`).
+- Variables in command position that expand to a subcommand keyword are now forbidden to fix a likely user error. For example ``set editor command emacs; $editor`` is no longer allowed (:issue:`10249`).
 - New option ``commandline --tokens-raw`` prints a list of tokens without any unescaping (:issue:`10212`).
 - An integer overflow in ``string repeat`` leading to a near-infinite loop has been fixed (:issue:`9899`).
 - ``string shorten`` behaves better in the presence of non-printable characters, including fixing an integer overflow that shortened strings more than intended. (:issue:`9854`)
 - ``string pad`` no longer allows non-printable characters as padding. (:issue:`9854`)
 - ``string repeat`` now allows omission of ``-n`` when the first argument is an integer. (:issue:`10282`)
+- ``functions --handlers-type caller-exit`` once again lists functions defined as ``function --on-job-exit caller``, rather than them being listed by ``functions --handlers-type process-exit``.
 
 Interactive improvements
 ------------------------
-- :kbd:`Control-C` during command input no longer prints ``^C`` and a new prompt but merely clears the command line. This restores the behavior from version 2.2. To revert to the old behavior use ``bind \cc __fish_cancel_commandline`` (:issue:`10213`).
 - Command-specific tab completions may now offer results whose first character is a period. For example, it is now possible to tab-complete ``git add`` for files with leading periods. The default file completions hide these files, unless the token itself has a leading period (:issue:`3707`).
-- The :kbd:`Control-R` history search now uses glob syntax (:issue:`10131`).
-- When the cursor is on a command that resolves to a script, :kbd:`Alt-O` will now open that script in your editor.
-- After using :kbd:`Alt-E` to edit the commandline in an external editor, the editor's cursor position will be copied over to fish. This is currently supported for Vim and Kakoune.
-- When deciding how to pass the cursor position to and from the external editor, :kbd:`Alt-E` now resolves aliases. For example use ``complete --wraps my-vim vim`` to synchronize cursors when `EDITOR=my-vim`.
-- Option completion now uses fuzzy subsequence filtering as well. This means that ``--fb`` may be completed to ``--foobar`` if there is no better match.
-- Nonprintable ASCII control characters are now rendered using symbols from Unicode's Control Pictures block.
+- Option completion now uses fuzzy subsequence filtering, as non-option completion does. This means that ``--fb`` may be completed to ``--foobar`` if there is no better match.
+- Autosuggestions were sometimes not shown after recalling a line from history, which has been fixed (:issue:`10287`).
+- Nonprintable ASCII control characters are now rendered using symbols from Unicode's Control Pictures block (:issue:`5274`).
+- When a command like ``fg %2`` fails to find the given job, it no longer behaves as if no job spec was given (:issue:`9835`).
+- Redirection in command position like ``>echo`` is now highlighted as error (:issue:`8877`).
+- `fish_vi_cursor` now works properly inside the prompt created by builtin ``read`` (:issue:`10088`).
+- fish no longer fails to open a fifo if interrupted by a terminal resize signal (:issue:`10250`).
+- ``read --help`` and friends no longer ignore redirections. This fixes a regression in version 3.1 (:issue:`10274`).
 
 New or improved bindings
 ^^^^^^^^^^^^^^^^^^^^^^^^
+- When the cursor is on a command that resolves to an executable script, :kbd:`Alt-O` will now open that script in your editor (:issue:`10266`).
+- Two improvements to the :kbd:`Alt-E` binding which edits the commandline in an external editor:
+  - The editor's cursor position is copied back to fish. This is currently supported for Vim and Kakoune.
+  - Cursor position synchronization is only supported for a set of known editors. This has been extended by also resolving aliases. For example use ``complete --wraps my-vim vim`` to synchronize cursors when `EDITOR=my-vim`.
+- ``backward-kill-path-component`` and friends now treat ``#`` as part of a path component (:issue:`10271`).
 - The ``E`` binding in vi mode now correctly handles the last character of the word, by jumping to the next word (:issue:`9700`).
+- Vi mode now binds :kbd:`Control-N`  to accept autosuggestions (:issue:`10339`).

 Other improvements
 ------------------
 - ``fish_indent`` will now collapse multiple successive empty lines into one (:issue:`10325`).
+- The HTML-based configuration UI (``fish_config``) now uses Alpine.js instead of AngularJS (:issue:`9554`).
+- ``fish_config`` now also works in a Windows MSYS environment (:issue:`10111`).

 - fish no longer links against the (n)curses library, opting to read the terminfo database via the terminfo crate.
   This means hashed terminfo databases are no longer supported. From our research, they are basically unused.
   When packaging fish, you likely want to add a dependency on the package containing your terminfo database instead of curses.
