I thought we were, but... I just applied this and it breaks t0103-log.sh
'no links with space in path'.

Having looked at it, our general printing of repo URLs falls foul of
that test - if you copy+paste it into t0101-index.sh then that fails as
well, and the tests are right to fail here.

Given that, I don't see the need to block this patch for introducing a
failure here (exactly the same failure will already exist on other
pages), but we should do something about the failing test case.

I propose squashing this in:
