Comment #1 on issue 2907 by [email protected]: Stems in TabStaff are not removed when manual beaming is used
http://code.google.com/p/lilypond/issues/detail?id=2907
A workaround by Marc Hohl: http://lists.gnu.org/archive/html/bug-lilypond/2012-10/msg00118.html A bit of investigating shows that \override Beam #'beamed-stem-shorten = #'(0 0 0) (and of course a \revert in tabFullNotation) solves the misplaced slur, but yield in the error message "No viable beam quanting found. Using unquanted y value." So this is considered a temporary hack.
