glissando between notes within a semitone and Staff/TabStaff problems

[Federico Bruni]

This is a follow up to this thread:
http://lists.gnu.org/archive/html/lilypond-user/2012-05/msg00245.html

I've just come across the same problem and I have a couple of questions:

1. lilypond, by default, doesn't show the glissando line between two noteheads positioned on the same staff line, because the end points are at the same height and the glissando thickness is not big enough to make it visible. Is this the expected behaviour?

2. AFAIK I cannot control the glissando in Voice without affecting also the glissando displayed in TabVoice. On the other hand, I can control glissando in TabVoice without altering the one in Voice. There's a workaround? (no tags please :-))
