The 'm' should be internationalized. I think the best way to do that is to build the entire expression (including the unit) in the python code, then you can use the i80n'd string that already exists [here](https://github.com/lonvia/waymarked-trails-site/blob/master/django/src/routemap/apps/routeinfo/views.py#L105).

And 'accumulated assent/descent' should be i80n as well.
