[dev] org-indent-mode patch

[Nicolas <n.goaziou@gmail.com>]

Hello,

I'd like to submit the following org-indent-mode patch for testing.

     git://github.com/ngz/org-mode-lists.git indent-patch-no-timer

It implements two things:

1. It indents correctly text when using visual-line-mode;
2. It removes the idle timer previous implementation was using, which
   means it won't refresh indentation more often than necessary.

Unfortunately, there is a price to pay:

1. Initialization will be much longer for large Org files, but I've
   added a message to the user saying so.
2. It is a bit slower, as the algorithm has more things to check.


Last point is obviously my main concern. Although not noticeable on my
not-so-recent laptop, I don't know how it behaves on old machines.

That's why a testing is necessary to determine (bugs and) if it is
usable. Any help welcome.

Regards,
