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

Allow nested square brackets again Code like echo $list[$var[1]] was producing an error because of nested square brackets. Allow these brackets again. Fixes #5362

Fix range expansion with negative ends If just one of the range ends is negative, this now forces direction away from it. I.e. if the beginning is negative, we go in reverse. If the end is negative, we go forwards. This fixes cases like $var[2..-1] if $var only has one element.

Remove "Array index out of bounds" errors This just removes every invalid index. That means with `set foo a b c` and the "show" function from tests/expand.in: - `show $foo[-5..-1]` prints "3 a b c" - `show $foo[-10..1]` prints "1 a" - `show $foo[2..5]` prints "2 b c" - `show $foo[1 3 7 2]` prints "3 a c b" and similar for command substitutions. Fixes #826.

expansion: Only clamp ranges when not forcing direction This caused `$var[2..-1]` to still expand to $var[1] if only one element was given. Fixup for #4965. Fixes #5187.

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.

Join variables by their delimiter in quoted expansion This switches quoted expansion like "$foo" to use foo's delimiter instead of space. The delimiter is space for normal variables and colonf or path variables. Expansions like "$PATH" will now expand using ':'.

Allow user to set and unset path property of variables This adds flags --path and --unpath to builtin set, analogous to --export and --unexport. These flags change whether a variable is marked as a path variable. Universal variables cannot yet be path variables.
