* posix/regcomp.c (parse_bracket_exp): Don't check for range if this is no option given the first token. * posix/regcomp.c (parse_bracket_exp): Fix test for EOS after hyphen in range expression. Return EBRACK in this case. * posix/regcomp.c (parse_bracket_element): Reject hyphens unless we expect them or it's the last element in the bracket expression. Indicated by new parameter. Adjust all callers. Prettier error messages.
