You have a strange human language.  In the  human languages I speak,
we usually say "If it is raining then we won't go outside." or "If it
is sunny then let's eat ice cream.".

We don't usually say "If it is true that it is sunny, then let's eat
ice cream.".  Saying such a locution would indicate that you don't
know yourself whether it's sunny or not, that you have been told so,
and that you don't believe it.

Well of course, it's a question of style.  If we had more powerful
editors(1), they could correct these stylistic variants as well as they
correct the indentation.



(1) actually, we have powerful enough an editor: emacs, the question
is whether we have enough time to customize it to do this kind of
things ;-)
