Re: bending: microtone TabNoteHeaded printed if in a chord

in `slur::draw-bend-arrow' there's the line
(ly:grob-set-property! right-tab-note-head 'transparent #t)
If you look at how right-tab-note-head is found, you'll notice that
the first typed note is taken and used as a starting point for the
tweaked slur and later on made transparent. Ofcourse this is not
enough while having a chord.

I think David answered already sufficiently.
But ofcourse it is not nice to use a tweak to _repair_ buggy
behaviour, better to kill the bug.

Should be straight-forward: make _all_ TabNoteHeads of the
target-chord transparent. See attached.
Look out for the comment:
;;;; Change next line to the (for-each ...) expression
Please note: I didn't check whether other definitions have the same weakness.

Well, I'm not the author, all merits to Marc Hohl.
Only working on it from time to time
