set override documentation

[Noeck]

Hi,

Is there any situation where I can use both and it is an advantage that
I can distinguish between them? Is there a difference for the user
(exept that it is a different thing internally)?

This page is a bit short:
http://www.lilypond.org/doc/v2.17/Documentation/notation/set-versus-override
This page tells me the difference:
http://www.lilypond.org/doc/v2.17/Documentation/notation/overview-of-modifying-properties
As long as there is no content on the first one, I would like to find
the paragraph 5.3.1 here: 5.3.5. Because the first time, I overlooked
5.3.1 and after seeing 5.3.5 I thought there is no explanation of the
difference.

This also concerns the stable documentation:

Cheers,
Joram
