Nick's a muppet (*and* perforce branching is hard, or at least hateful,
in as much as a branch spec is merely a shorthand - it's actually all
a flat namespace underneath). So this shouldn't be here, but it's all
due to a transcription typo on my part in the integrate command.
Whereas the branch spec I carefully made is valid, but no $expletive
use in actually creating the $expletive branch.
Doesn't excuse my mistake. But does explain it.
