Not just written pitch.  Everything.

No, to specify the transposition of an instrument.  That's nothing that
you can change.

It changes the audible pitch _along_ with the written pitch.  At least
if we are talking 2.17.13 or later (cf issue 754 in the tracker
<URL:http://code.google.com/p/lilypond/issues/detail?id=754>).

The behavior before that was plain nuts.  There were usage patterns
based on this behavior, but nobody really understood why they worked,
and when and how they broke down.
