Cutting tool for line

Original Redmine Issue: 4559
Affected QGIS version: master
Redmine category:digitising

When I use the tools for separate entity, I expect to obtain 2 entities. But if the line cross itself at some(s) place(s), I obtain a new entity between each crossing point. The line act as a cutting tool applied to itself.

I don't know if it's a bug or if this comportement is what you expect. For me it's a bit annoying. I edit line that come from a GPS receiver held by hiker. When they stop during the survey, and they often do, the GPS accumulate a lot of point almost at the same position, creating a lot of self-crossing. When I cut anywhere on this line, QGis separate the entity in a very big lot of entities.

The line is also split in every self-intersection point.
