09d4de6a1b Issue 815: Cannot add segment to Path after removing last segment 
Fixed an issue where after removing the last segment of a path,
new segments cannot be re-added.

Added new Path Curve test cases to test the difference between
a path with one and no segments (zero curves in both cases), which
catches the bug.
