Victor, what changes to the doc strings are you talking about? Adding descriptions of the parameters, maybe? Other than that they look very similar to me.
I haven’t looked closely, but the Python doc strings have been updated at least once more than the C doc strings: r54666 and Issue 1602378. So if you are copying anything, it might be better to copy from Py to C. But I would do that separately.
The doc strings and reference documentation just seem to have been added independently: ce2d120c3903 (main documentation) vs 67b3ac439f64 (doc strings)
