CHANGELOG: Reorganize a bit
The builtin-buffering thing is huge and should be early in the big ticket items, the performance improvement to completion of commands is cool but not all that important. [ci skip]

------------------------------
|

|
||||
- Undo and redo support for the command-line editor and pager search (#1367). By default, undo is bound to Control+Z, and redo to Alt+/.
|
||||
- builtins may now output before all data is read. For example, ``string replace`` no longer has to read all of stdin before it can begin to output.
|
||||
This makes it usable also for pipes where the previous command hasn't finished yet, like::
|
||||
|
||||
# Show all dmesg lines related to "usb"
|
||||
dmesg -w | string match '*usb*'
|
||||
|
||||
- A new variable, ``fish_kill_signal``, is set to the signal that terminated the last foreground job, or ``0`` if the job exited normally (#6824).
|
||||
- Control-C no longer kills background jobs for which job control is
|
||||
disabled, matching POSIX semantics (#6828).

Syntax changes and new commands
|

-------------------------------
|
||||
- Range limits in index range expansions like ``$x[$start..$end]`` may be omitted: ``$start`` and ``$end`` default to 1 and -1 (the last item) respectively.
|
||||
- Logical operators ``&&`` and ``||`` can be followed by newlines before their right operand, matching POSIX shells.
|
||||
- A new ``fish_is_root_user`` simplifies checking for superuser privilege, largely for use in prompts (#7031).
