It's also allowed behaviour. '-' is a valid URI character, so any user
agent that chops them off the end of a URI is broken. I realise that
doesn't help the people using them, but it would be better to fix the
problem in the correct place.

Having said that, it looks like geohashes use [a-z0-9] which would avoid
these problems.
