Of course you are right, if you think LilyPond should do it in a strict
"stubborn" way.  :)

Agree.

There I don't agree anymore.
You are reasoning in a "developer-mind", where I'm reasoning as a
"lambda" user.  My idea is closer to Reinhold's thoughts (but not
exactly the same, see below).

I have no statement about this "cuisine interne"-stuffs.

That's exacly what I think!

In a strict way, yes.
In a "practical" way, no.

Imagine somebody changes the text to "cresc. poco a poco" but still
ends it on the second note (which is an abhorrence, we all agree).
Then the second note would be incredibly shifted!
No, I don't think DynamicTextSpanner should behave like \textLengthOn .

Yeah, that's what I meant by saying this is a pure "theorical case"
(but however could be used in practise).

BTW when  http://lists.gnu.org/archive/html/lilypond-user/2010-05/msg00171.html
will be fixed, I'll certainly come again to request
"*without dashed line*" cresc by default for \cresc ...  ;D

Yes (but since it prints the "cresc." I'm not sure the warning is
really necessary).  OK, in strict way, yes it is.

Thanks everybody for your attention.

Cheers,
Xavier
