Comment #3 on issue 2475 by [email protected]: GSoC page hammer-on and pull-off are already implemented
http://code.google.com/p/lilypond/issues/detail?id=2475
There's already issue 2594, which aims at fixing the missing documentation for hammer-on and pull-off.
This issue can be closed, as the tablature item has been removed from GSoC page (probably because - this is my guess - Carl is not available for mentoring anymore?).
