[QGIS-Developer] Processing: No spatial index exists for input layer, performance will be severely degraded

[Luigi Pirelli]

I've this message constantly... but usually when an intermediate layer is
used in some geoprocess. So, you can just add a "create spatial index" step
before the next geoprocess. Doing it automatically can be time spending. Do
you really need it everytime?
