Ok, but what about the errors in my original post? I should make sure
all unittests pass when I make a pull request, right?

If that's required I think I'd have to first checkout an older commit.
But I'm not sure which one. There's a bunch of them for dates May 16th
and older listed here:

E.g. this one: http://d.puremagic.com/test-results/test_data.ghtml?dataid=62436
It says:
>From git://github.com/D-Programming-Language/phobos
   3b628ae..d1d8124  master     -> origin/master

I'm not sure what 3b628ae..d1d8124 means, should I do "git checkout
d1d8124" or something similar to get this commit?
