[Talk-GB] Advice please: Goat tracks in mountain areas

[Elizabeth Oldham]

The path is clear over most of its length on (JOSM's) Bing aerial 
photography, less so at the western end where it joins the Pyg Track.

It doesn't look like a goat or sheep trod, it looks like a desire line 
or ordinary mountain path. Backed up with heat traces on Strava. I'd 
certainly map it - it's what's on the ground.

sac_scale tag seems appropriate information for renderers to decide if 
they want to draw it or not.
