10961	Wrong turns generated by get_turns() for Linear spikes.	awulkiew	awulkiew	"1. For L/A:
{{{
""LINESTRING(7 8, 6 10, 10 2)""
""POLYGON((0 0,0 10,10 10,10 0,0 0))""

""LINESTRING(7 8, 6 10, 11 0)""
""POLYGON((0 0,0 10,10 10,10 0,0 0))""
}}}
for intersection point `(6 10)` u/u is generated instead of i/u.

2. For L/L:
{{{
""LINESTRING(6 0,0 0,5 0)""
""LINESTRING(2 0,0 0,-10 0)""
}}}
for intersection point `(0 0)` only one, wrong turn is generated (a spike is not detected as a spike).

3. For L/L
{{{
""LINESTRING(-7 -8,3 0,4 -1,-7 10)""
""LINESTRING(-5 -4,3 0,4 -1,7 -4,2 -1)""
}}}
