Number of messages in a thread

[Asif Iqbal <vadud3@xxxxxxxxx>]

Hi All

I know that I can use %M to display the total number of messages. But
if I choose to display the number like this (%M) I also see some empty
(  ) -parenthesis  when there is only one message and no thread.

Is there a way I can display like this:

for 2 messages in a thread display (2)
for 1 message in a thread display nothing

Also how do I put different color than default for message with threads?

Thanks for the help
