don't check status of symbol as variable when parsing at top level (bug #60882)
* lex.ll (base_lexer::handle_identifier): Don't check whether
identifier is a top-level variable. Matlab apparently doesn't check
either, so the behavior is the same whether at the command line or in
a function or script.
