I wouldnt bother with the slurs at all, not in the last part because
your bends will likely break if someone ever decides to refactor the
slur code.

Just write a simple grob that is composed of two line segments to make
the pointed bend.  Have you already thought of how the spanner should
behave when it crosses a line break?  Have a look at tuplet-spanner.cc
for some inspiration (tuplet spanner is probably more complex than you
need; you can just have a right and left span point).

You'll probably need entirely different code for the tab version,
including different grob code, and a different engraver.  I recommend
worrying about that once the pointed-brace version is completely
working.
