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.
