Comment:
I think you are right. I tried it before applying patches, saw that
something was not right but did not copy the output. When I tried again
after removing the patches (using hg qpop and sage -br) it still works!
But I just tried again on another machine, still 4.6.alpha3, and with no
patches the load command gives
{{{

It's a mystery that popping the patches left a setup in which the load
works; and that left open the possibility that the only reason why the
second patch worked was that the effect of the first patch was still
around (!) so on the second machine I applied the second patch without
previously applying the first, and that still worked.
Moreover, then popping the second patch put the system back properly (the
load again fails).
So I am giving the *second* patch a positive review.
