Comment:

 Here we go again

 I'm sorry to admit that the patch is still not tested properly. I will try
 to get time to understand more about how to build the tests, but if
 someone have the possibility to help it would be great.

 In the patch is the functions:
 ST_ShortestLine(geometry, geometry)
 ST_LongestLine(geometry, geometry)
 ST_Max_Distance(geometry, geometry)
 ST_DFullyWithin(geometry, geometry, double precision)

 I have tried to reflect the correct in
 doc/reference.xml
 postgis.sql.in.c
 uninstall_postgis.sql.in.c

 The new approach to the distance-calculations seems to be more efficient
 in iterating through the vertexes. When using it on big geometries with
 many vertexes it will be significant faster, but on small geometries there
 is almost no difference.
