[FYI,1/2] Fix use-after-free in number_or_range_parser
Commit Message
-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.

* cli/cli-script.c (read_next_line): Pass 0 as repeat argument to
command_line_input.
