arm_hug and arm_holding

Same tag or what? arm_hug seems to have mostly "couples" and whatnot with one holding onto the other's arm, while arm_holding also has other kind of images, from sex stuff where he holds her by her arms, to solo pics etc.

They seem to be the same thing to me. I prefer arm_holding because it goes with hand_holding.

This seems to have been brought up in forum #23741, but was left unresolved.
