I'm sorry, I (still) don't have enough knowledge of Emacs to delve
into such questions.

I reported this bug as a mere user, hoping that you (the maintainers),
if agree with my reasoning, make the suitable changes to the program.

In the case at hand, what I reported is quite simple, I think: from
"emacs -Q" (transient mark mode on) visit some C file, select some
fragment of code and type TAB.

Hopefully you'll see the same behavior as me:
* If the code in the region was already well indented, nothing happens
and the mark remains active.
* Else, the code is indented and the mark is deactivated.

What I say is that the mark should be deactivated _always_ at the end
of the command, because the "transient" operation (revise the
indentation of those lines) is done.

This is so obvious to me that I'm surprised of seeing you so
hesitant...  but well, you decide :)
