Fix use-after-free in number_or_range_parser
-fsanitize=address showed a use-after-free in number_or_range_parser. The cause was that handle_line_of_input could stash the input into "saved_command_line", and then this could be freed by reentrant calls. This fixes the bug by preventing commands that are read by "commands" from being eligible for repeating. gdb/ChangeLog 2018-08-17 Tom Tromey <tom@tromey.com> * cli/cli-script.c (read_next_line): Pass 0 as repeat argument to command_line_input.
