We disagree.  There could be a useful "H" help option.

Use a command line option: --git.

All command line options apply to create the initial list of
displayed names.

Or add code to set

	$git-fallback = 1 if $interactive;

I think it's not worth it.

Only about 2% of signatures in git history are reviewed-by:

Using S shows the signature type.

Over the last year:
$ git log --since=1-year-ago | grep -i "by:.*@" | \
  cut -f1 -d":" | sort -i | uniq -ci | sort -rn | head -10
  83413     Signed-off-by
   6544     Acked-by
   2022     Reviewed-by
   1691     Reported-by
   1065     Tested-by
    111     Reported-and-tested-by
     83     Suggested-by

Maybe.  I think it doesn't matter much though.
Menu handling code tends to get long.

I think it needs to be a function.
I want a 0 or 1, not "" or 1.
