There's a segfault bug in 11/11, which wasn't found because the test
suite doesn't test `git fetch <url>` just `git fetch <named>` and this
is handled differently.

I'll send a fix soon, but don't merge this down from pu for now.

In order to test for that I brought that cmdline quoting patch back, I
can't find a better way to do that, and in addition I have this similar
WIP patch:

It'll be amended a bit more, but the general idea is there, because of
how this whole quoting mess looks like I have to resort to the above
hack outside of the test setup.
