[Tagging] natural=ridge vs natural=arete

[Richard Z.]

Hi,

following some discussions on github (1) and talk-at (2) I have tried
to clarify the definition of natural=ridge in the wiki
  http://wiki.openstreetmap.org/w/index.php?title=Tag:natural%3Dridge&diff=1104725&oldid=998905

Not sure if this is good enough, personaly I would prefer a single ridge 
key with additional subkeys denoting properties such as gentle,sharp, cliff
ridges.
