Osm:Wmthelp-rendering.hikinglabels/en

The label for each route is "guessed" from the tags in the following order:

1. Check for [localized rendering rules](rendering/hikinglocal). 2. Try to interpret the `osmc:symbol` tag. For details about which parts are understood, see [osmc:symbol rendering rules](rendering/osmc). 3. If a `ref` tag exists, make a text label with the `ref` tag. 4. If a `name` tag exists, derive a reference from that, first by using only upper-case letters and failing that by using the first letters of the name. 5. Give up.
