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. 2014-08-21 13:01:24 +08:00			`Array index out of bounds`

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. 2014-08-21 15:26:14 +08:00			`Invalid index value`
