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.
