Ok, done.

Done.

Hm, Neil proposed to use a more descriptive name for this property, IIUC.
Done.

Done.

I just copied the code from scm/output-lib.scm similar to the parenthesizing
routine within scm/tablature.scm. I thought I could call the newly 
introduced
helper routine itself, but this is not possible due to the limitation 
that I can't
(at least easily?) get the current property values of the 
HarmonicParenthesesItem
grob within the tie callback.
parenthesize-stencil (in scm,/stencil.scm) does not take the whiteout 
into account,
and at the moment, the whiteout handling is not done properly throughout
scm/tablature.scm. Sometimes it is hardcoded, sometimes it takes the
'whiteout property into account. I think the brackets and parentheses
should follow the TabNoteHead #'whiteout more consequently in this respect.


I'll shut down my computer for now - today he seems to hate me ;-)
I had to redo my patch sets and did a partial revert of a former patch,
no idea why this happened ...
