builtin-notes: Minor (mostly parse_options-related) fixes
Use PARSE_OPT_NONEG to disallow --no-<option> for message, file, reedit-message and reuse-message. for which --no-<option> does not make sense. This also simplifies the code in the option-handling callbacks. Also, use strbuf_addch(... '\n') instead of strbuf_addstr(... "\n") in couple of places. Finally, improve the short-help by dividing the options into two OPT_GROUPs.
