Comment:
Sorry, but neither of the patches applies to a fresh build of
sage-4.3.alpha0.
But it could actually be that my sage-4.3.alpha0 has a problem. After
building it, I did
./sage -clone infinitepoly
waited 8 hours, but it wasn't finished. It seems that it hanged while
trying to do the documentation. Eventually, I pressed Ctrl-C (was needed
several times).
The clone seemed to work, though. But:

OK, back, ./sage -br main.

OK, what are the changes?
{{{
sage: hg_sage.diff()
cd "/home/SimonKing/sandbox/sage-4.3.alpha0/devel/sage" && hg diff | less
(END)
}}}
No changes, then, but there are uncommitted changes. Frustrating.
Conclusion: I can not give a positive review, of course, but the problem
seems to be deeper, so, it isn't "needs work" either. I'll mark it "needs
review".
