4acea72700 New -n option for read builtin 
Usage: read -n nchars
Reads maximum of nchars characters. If nchars <= 0, there's no limit.

1c4223889b Fix test output for complete -e tests 
GNU sort behaves stupidly when LC_ALL is not C. This caused the test
output to be sorted wrong.

7fce9e2411 Trim trailing newline on cmdsubst when IFS='' 
When $IFS is empty, command substitution no longer splits on newlines.
However we still want to trim off a single trailing newline, as most
commands will emit a trailing newline and it makes it harder to work
with their output.

2974025010 Fix error span for invalid slice indexes 
The span now properly points at the token that was invalid, rather than
the start of the slice.

Also fix the span for `()[1]` and `()[d]`, which were previously
reporting no source location at all.

cc49042294 Parse slices even for empty variables 
When a variable is parsed as being empty, parse out the slice and
validate the indexes anyway, behaving for slicing purposes as if the
variable had a single empty value.

Besides providing errors when expected, this also fixes the following:

    set -l foo
    echo "$foo[1]"

This used to print "[1]", now it properly prints nothing.

3981b644d6 Fix double expansions ($$foo) 
Double expansions of variables had the following issues:

* `"$$foo"` threw an error no matter what the value of `$foo` was.
* `set -l foo ''; echo $$foo` threw an error because of the expansion of
  `$foo` to `''`.

With this change, double expansion always works properly. When
double-expanding a multi-valued variable, in a double-quoted string the
first word of the inner expansion is used for the outer expansion, and
outside of a quoted string every word is used for the double-expansion
in each of the arguments.

    > set -l foo bar baz
    > set -l bar one two
    > set -l baz three four
    > echo "$$foo"
    one two baz
    > echo $$foo
    one two three four

973dd6ffbd read: Support arrays, character splitting 
Enhance the `read` builtin to support creating an array with the --array
flag. With --array, only a single variable name is allowed and the
entire input is tokenized and placed into that variable as an array.

Also add custom behavior if IFS is empty or unset. In that event, split
the input on every character, instead of the previous behavior of doing
no splitting at all.

cfa13ed84c Update tests for new type behavior 
One of the tests was using `>/dev/null` to suppress the `type` output.
That needs to be `^/dev/null` now, but instead just go ahead and use the
new `-q` flag.
