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

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.

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.
