[Denemo-devel] Undo status

[Richard Shann]

This is the only known bug in Undo:


(d-NotationMagick-TwelveToneRow)
(d-MoveToMeasureLeft)
(d-MoveCursorRight)
(d-StageForUndo)
(d-SplitMeasure)
(d-Undo) ; Undo works
(d-MoveCursorLeft)
(d-MoveCursorLeft)
(d-StageForUndo)
(d-SplitMeasure)
(d-Undo) ; leaves an empty measure


This should return to the twelve tone row inserted at first, but does
not because of a positioning error:

** (denemo:13506): WARNING **: Could not find position for undotype 2  movement 
1 staff 1 measure 3 object 2 appending 0 offend 0

It is trying to find object position 2 in a measure which I think is
empty. Note the d-StageForUndo calls, which stop the d-Undo from
stepping right back to the start of the script.
