This adds string-x.rst for each subcommand x of string. The main page
(string.rst) is not changed, except that examples are shown directly after
each subcommand. The subcommand sections in string.rst are created by
textual inclusion of parts of the string-x.rst files.
Subcommand man pages can be viewed with either of:
```
man string collect
man string-collect
string collect <press F1 or Alt-h>
string collect -h
```
While `string -h ...` still prints the full help.
Closes#5968
This adds support for `fish_trace`, a new variable intended to serve the
same purpose as `set -x` as in bash. Setting this variable to anything
non-empty causes execution to be traced. In the future we may give more
specific meaning to the value of the variable.
The user's prompt is not traced unless you run it explicitly. Events are
also not traced because it is noisy; however autoloading is.
Fixes#3427
Someone has hit the 10MiB limit (and of course it's the number of
javascript packages), and we don't handle it fantastically currently.
And even though you can't pass a variable of that size in one go, it's
plausible that someone might do it in multiple passes.
See #5267.
Brace expansion with single words in it is quite useless - `HEAD@{0}`
expanding to `HEAD@0` breaks git.
So we complicate the rule slightly - if there is no variable expansion
or "," inside of braces, they are just treated as literal braces.
Note that this is technically backwards-incompatible, because
echo foo{0}
will now print `foo{0}` instead of `foo0`. However that's a
technicality because the braces were literally useless in that case.
Our tests needed to be adjusted, but that's because they are meant to
exercise this in weird ways.
I don't believe this will break any code in practice.
Fixes#5869.
We were flip-flopping between the two terms, so we now use one. We
still mention "array" in the chapter, and it's still `read --array`,
though.
Fixes#5846.

fish_indent_lexer formats lines not starting with a prompt indicator
as output, as long as there is a prompt indicator elsewhere.
So these tags are useless and wrong.
See #5696.

There's an explicit label for "cartesian-product", but the title is
"Cartesian Product*s*". So linking via with `thing <#link>`_ links the
title, so without the "s" it doesn't work.
From what I know, linking via :ref:`thing <label>` is preferred and
works better with other exports and across files?
I think I should take a doc holiday.

This adds a reference to one specific FAQ, so it adds a label for that
one question. It does not add the rest, because they currently aren't
linked. If you add a reference to an FAQ, you should add the label as
well.
