No. I want the indentation to be proper. It cannot be child of a later message.

As we can see this is not possible. Becase the second last message came
after the last one.

Wow. Good pointer. The default value of the variable is 'adopt'. I
experimented with the other three possible values. And here are the
results, along with the quoted docstring

(setq gnus-summary-make-false-root 'none)

I think 'none' and 'empty' works best for the situation. May be I should
try each of these for a couple of days and decide.
