 it would be nice to keep a method to import exact data, even if splitting
 will be the default.

 how would it be split? after a certain number of vertices of a polyline
 like v.split or every "n" map units in a grid like v.in.gshhs?


 note v.generalize currently requires to run v.build.polylines first to get
 correct output. I don't know if that is a feature or a bug.
 but if breaking polylines was the default for v.in.ogr it could become a
 widespread subtle problem for it.
