Not really happy with this one. I've been careful to keep ui largely
unaware of Mercurial's implementation details. The biggest exception is
path handling, and I've been planning to pull that out too. If we start
putting helper functions in ui, it's going to burst a dam and ui is
going to grow dozens of random helpers and become very ad-hoc.

Couldn't we just update a node._shortdigits?
