Not discussed, includes a new thing that queries the terminal for the client OS
when what is really needed is just a `uname` - which would also work on Terminal.app.

For compound commands we already have begin/end but

The difference from {} can break muscle memory and add extra steps
when I'm trying to write simple commands that work in any shell.
Fix that by embracing the traditional style too.
---
Since { and } have always been special syntax in fish, we can also
allow
{ }
{ echo }
which I find intuitive even without having used a shell that supports
this (like zsh. The downside is that this doesn't work in some other
shells. The upside is in aesthetics and convenience (this is for
interactive use). Not completely sure about this.
---
This implementation adds a hack to the tokenizer: '{' is usually a
brace expansion. Make it compound command when in command position
(not something the tokenizer would normally know). We need to disable
this when parsing a freestanding argument lists (in "complete somecmd
-a "{true,false}"). It's not really clear what "read -t" should do.
For now, keep the existing behavior (don't parse compound statements).
Add another hack to increase backwards compatibility: parse something
like "{ foo }" as brace statement only if it has a space after
the opening brace. This style is less likely to be used for brace
expansion. Perhaps we can change this in future (I'll make a PR).
Use separate terminal token types for braces; we could make the
left brace an ordinary string token but since string tokens undergo
unescaping during expansion etc., every such place would need to know
whether it's dealing with a command or an argument. Certainly possible
but it seems simpler (especially for tab-completions) to strip braces
in the parser. We could change this.
---
In future we could allow the following alternative syntax (which is
invalid today).
if true {
}
if true; {
}
Closes#10895Closes#10898
And leave the old behavior under the name "cancel-commandline".
This renames "cancel-commandline-traditional" back to
"cancel-commandline", so the old name triggers the old behavior.
Fixes#10935
On ctrl-l we send `\e[2J` (Erase in Display). Some terminals interpret
this to scroll the screen content instead of clearing it. This happens
on VTE-based terminals like gnome-terminal for example.
The traditional behavior of ctrl-l erasing the screen (but not the
rest of the scrollback) is weird because:
1. `ctrl-l` is the easiest and most portable way to push the prompt
to the top (and repaint after glitches I guess). But it's also a
destructive action, truncating scrollback. I use it for scrolling
and am frequently surprised when my scroll back is missing
information.
2. the amount of lines erased depends on the window size.
It would be more intuitive to erase by prompts, or erase the text
in the terminal selection.
Let's use scrolling behavior on all terminals.
The new command could also be named "push-to-scrollback", for
consistency with others. But if we anticipate a want to add other
scrollback-related commands, "scrollback-push" is better.
This causes tests/checks/tmux-history-search.fish to fail; that test
seems pretty broken; M-d (alt-d) is supposed to delete the current
search match but there is a rogue "echo" that is supposed to invalidate
the search match. I'm not sure how that ever worked.
Also, pexepect doesn't seem to support cursor position reporting,
so work around that.

Before, it unnecessarily stated that there are three `--style` options, when
there are actually four.
I also align the default `--style=script` argument to the beginning of the line
to match the other options visually for easier scanning.
* Pass path to install()
It was dirty that it would re-get $HOME there anyway.
* Import wcs2osstring
* Allow installable builds to use a relocatable tree
If you give a path to `--install`, it will install fish into a
relocatable tree there, so
PATH/share/fish contains the datafiles
PATH/bin/fish contains the fish executable
PATH/etc/fish is sysconf
I am absolutely not sold on that last one - the way I always used
sysconfdir is that it is always /etc. This would be easy to fix but
should probably also be fixed for "regular" relocatable builds (no
idea who uses them).
An attempt at #10916
* Move install path into "install/" subdir
* Disable --install harder if not installable
This is fairly subtle.
When installable, and we either can't find the version file or it is
outdated, we ask the user to confirm installation (just like `--install`).
We do that only if we are really truly interactive (with a tty!) to
avoid `fish -c` running into problems.
This check could be tightened even more, because currently:
```fish
fish -ic 'echo foo'
```
asks, while
```fish
fish -ic 'echo foo' < /dev/null
```
does not.
`fish -c` will still error out if it can't find the config, but it
will just run if it is out of date.
These are another way to spell the same thing that doesn't match what
`bind` would print.
They're also not documented and tested thoroughly.
Since they are just small shortcuts and unreleased we can just remove
them.
Fixes#10845
alt-e restores the cursor position received from the editor, moving by
one character at a time. This can be super slow on large commandlines,
even on release builds. Let's fix that by setting the coordinates
directly.
Part of #1842
It's like jump-to-matching-bracket, but jumps right before the bracket
I will use it to mimic vi 'ab' and 'ib' text objects in the next commit
Given complicated semantics of jump-till-matching-bracket, an alternative name
could be 'jump-inside-matching-brackets'. But that would make names non-symmetrical.
I'm not sure what is worse.
Add round options, but I think can also add floor, ceiling, etc. And
the default mode is trunc.

fish_add_path can be used either interactively, in the commandline,
or in config.fish. That's its greatest strength, it's a very
DWIM-style command.
One of the compromises that entails, however, is that it can't really
be very loud about what it does. If it skips a path, it can't write a
warning because it might be used in config.fish.
But it *can* if it's used interactively. So we try to detect that case
and enable verbose mode automatically.
That means if you do
```fish
fish_add_path /opt/mytool/bin/mytool
```
it may tell you "Skipping path because it is a file instead of a
directory:".
The check isn't perfect, it goes through status current-command and
isatty, but it should be good for most cases (and be false in config.fish).
Use "directories" explicitly instead of "components" to make it more
clear that the arguments need to be directories, not files.
Also a bit on intent and variable scope.
This allows running `set` without triggering any event handlers.
That is useful, for example, if you want to set a variable in an event
handler for that variable - we could do it, for example, in the
fish_user_path or fish_key_bindings handlers.
This is something the `block` builtin was supposed to be for, but it
never really worked because it only allows suppressing the event for
the duration, they would fire later. See #9030.
Because it is possible to abuse this, we only have a long-option so
that people see what is up.
This allows making something like
```fish
abbr --add gc --position anywhere --command git back 'reset --hard
HEAD^'
```
to expand "gc" to "reset --hard HEAD^", but only if the command is
git (including "command git gc" or "and git gc").
