Just one last question (Promise)

abc only provides one decorator for bends, i.e. +bend+

Should this be interpreted as a 'Bend up' or a 'Bend up and Down'?
Whichever is chosen will be the default type of bend throughout the program.

HARMONY will provide both as options, plus Pre-bend (Bend down from an initial bend-up position). But it can only export one type to abc within the standard.
