according with Richard, we think that having the link

https://docs.qgis.org/testing/en/docs/user_manual/processing_algs/qgis/vectoroverlay.html#qgisintersection

so provider name concatenated with algorithm name is the way to go. To
avoid any other future issues with hyphens vs underscores etc I think it
is smart to have a single string like `qgiscountpointsinpolygon` instead
of `qgis_countpointsinpolygon`.

This way the name of the algorithm should be always unique even among
providers.

I'm sorry that we did not face these issues before, but nobody thought
we can have this sphinx troubles with anchors.


Thanks Alex for taking care of this

Cheers

Matteo
