javascript diff_cleanupSemantic uses negative indexes in the equalities array #89

Open GoogleCodeExporter opened 8 years ago

javascript diff_cleanupSemantic uses negative indexes in the equalities array.

This is because it equalitiesLength is allowed to go into a negative range.

Normally this doesn't cause any problems, because it will just be stored as a 
property on the array, but Safari 1.5.x seems to have some issues and doesn't 
always get the value that's stored in equalities[-1] back out. (Or perhaps it 
didn't properly go in in some cases.)
