Thanks Giuseppe,
I actually can see that the "Close Gaps with Spline" is mentioned in the
documentation, but no further info is proposed.

Asking the SAGA CMD I can only get the usage (which I already knew from
`rsaga.get.usage(lib="grid_tools", module=7)`:

$ saga_cmd libgrid_tools.so "Close Gaps"
