We are 1-indexed, and so it's weird to have `test` count its arguments
from 0.
For `test 1 =` this changes the error from
test: Missing argument at index 2
1 =
^
to
test: Missing argument at index 3
1 =
^
test loves error messages like
test: Missing argument at index 2
without explaining where that "index 2" is.
So now, we print the arguments below that, with a caret pointing to
the place where the error occured.
For example:
> test 1 = 2 and echo true or echo false
test: Expected a combining operator like '-a' at index 3
1 = 2 and echo true or echo false
^

* docs/faq: Mention prepend_sudo
[ci skip]
* __fish_prepend_sudo: Use $history[1] if commandline is empty
Currently, if you press alt+s with an empty commandline, it inserts
"sudo", which seems fairly useless.
Now, it inserts "sudo " followed by the last history entry, which
makes it a replacement for `sudo !!`.

There's a terrible number of fishscripts that start with
set path (dirname (status filename))
And that's really just a bit boring.
So let's let it be
set path (status dirname)
This reverts commit 1b0ec21773.
"Interactive" has multiple meanings here, one of them being "the whole shell" is interactive, which `status is-interactive` tests, and one "this interaction is interactive", which happens when `read`ing in a script.
Fixes#7080.
This change is necessary to fix dynamic titles for the Alacritty
terminal. We do this by simply adding the (wchar_t *) literal
L"alacritty" to the end of the title_terms array. This variable is
ultimately used in the subsequent function
does_term_support_setting_title (dtsst) for the purposes of whitelisting
certain terminals.
If an Alacritty user does not have the terminfo for alacritty present in
their terminfo database, Alacritty sets the TERM variable to
"xterm-256color", but if the terminfo for Alacritty is present, TERM is
instead set to "alacritty".
Prior to this change, none of the "fallback patterns" in the dtsst
function (which is used to ultimately decide whether or not a given
value of the TERM environment variable is supported) would apply to a
value of "alacritty". Ordinarily, the dtsst function would return true
if nothing matches, but one of the final checks involves testing the
result of ttyname_r to see if it contains the substring "tty", which
causes dtsst to return false. In the case where TERM="alacritty", this
is erroneous, because Alacritty does, indeed, support changing its title
and will also silently ignore attempts to change the title if that
behavior has been disabled by the user [1].
The changed file, src/env_dispatch.cpp, was reformatted by clang-format
in accordance with the documented procedures for contributors.

When fish exits, it tries to restore the foreground process group.
However this may actually steal control of the fg process group
from another process. Fix this by clearing the SIGTTOU handler so
that tcsetpgrp() will fail.
Credit to @mqudsi for awesome debugging.
Fixes#7060
Prior to this change, if the user's prompt was wider than the terminal, we
would reduce it to just `> `. With this change, attempt to truncate the
prompt.
For each line of the prompt, calculate its width. If the width exceeds
COLUMNS, prepend ellipsis to that line, and start removing characters
until it fits. Escape sequences are skipped.
Fixes#904
Initially I wanted to pick a different name to avoid confusion with
process groups, but really job trees *are* process groups. So name them
to reflect that fact.
Also rename "placeholder" to "internal" which is clearer.
Prior to this, jobs all had a pgid, and fish has to work hard to ensure
that pgids were inherited properly for nested jobs. But now the job tree
is the source of truth and there is only one location for the pgid.
job_lineage was used to track "where jobs came from" but the job tree idea is
a better abstraction. It groups jobs together similar to how a process group
would in other shells. Begin to remove the notion of lineage.
