I do not pretend that I understand everything. I do not see any obvious
problem. I agree that it is better to have the same code in 3.5 and 3.6
in this case => pushed to 3-5 branch, see
Note that I removed the hunk:

IMHO, it was just a debugging output.
Hmm, I think that it is too risky to push it into 3-5-6 for 3.5.6-rc2.
So, it needs to wait for 3.5.7. Well, we will at least get some feedback
from 3.6.0 users in the meantime.
