Always lex braces and brackets as separate tokens The lexer needs to always return braces and brackets separately so that the parser can decide if they are part of some construct like an array subscript or a variable expansion. This means that there was no point in moving bare-word tokenization into the external scanner. I've moved it back into the normal scanner. The tricky part is how to deal with the separate '}' and ']' tokens in the case where they are *not* part of a subscript or an expansion. For example, in code like `echo {hi}`, the syntax tree should still clearly indicate that only *one* argument is being passed to echo. For now, we achieve this by grouping the '{', hi, and '}' tokens into a single `concatenation` node, which is a bit odd, but it's the best we can do.
